I have basically the same setup using DNA UEL header and exhaust on a 2001 Subaru Outback Limited SUS (Sedan) which has the EJ251. Had to do a small modification to the header to make it fit correctly, but it was very easy to get done.. and would definitely do it again. Anyone else out there looking for a similar setup, do it man.. pretty awesome results for non-turbo apps
I have a similar setup on my 07 2.5i, but I'm using a 9 inch dynomax race bullet muffler, no resonator and stock single cat from an 04 impreza. I also disabled any cat/o2 related code using ECU flash so no CEL at all lol
Sounds amazing man!! I'm currently in the process of installing headers on my 07 2.5i and after seeing your results, I really can't wait to have them on!!
+Gérémy Desjardins hell yeah bro thanks! I hope this was informative and more n/a subie achieve "subie rumble". What headers are you buying? And your going to love it I sure did!
Really informative thanks!! I bought a used set of headers, probably ebay stuff, that were already made for a 2007 Impreza. It has a Hi-Flow cat and now I just need to figure out what I'll be doing for the Catback.
Jose, I did this for my 06 2.5i as well. CEL came on once in a while because of the High Flow cats, if you run stock 02-05 2.5rs cats you won't get the CEL but if you run the High Flow then you're going to need the O2 cat simulator piece( bigdaddiesgarage.com/ ) that website sells the part pretty cheap, I installed it on my High Flow and never got the CEL again. It happens because the High Flow Cat does not get hot enough to burn the excess exhaust enough, so the part that simulates the Cat heats up and the O2 reads that it is hot enough, so you won't be running the engine on RICH all the time when the CEL is on. But yeah, if the Tsudo system is too expensive then just run the 98-05 2.5rs UEL headers, catalytic converters and extend the 06-07 O2 sensors. I still have the 2.5i but I also have a 05 2.5rs with a Borla Uel headers, random cat high flow cat and nVidia 3" cat back exhaust and an Injen CAI, all I have left to do is take it in for a tune, get as much as I can out of it. I have been told that the O2 simulator part works on straight pipes too, I never tried it, but I read up on people with Mustangs, Camaro's and Corvette's running them just fine.
yea i wanted to bolt up an oem catalytic from an 02-05 rs but they are very expensive $200-250. Well i have a simulator that came with the high flow cat but doesn't have the cones like design inside. I have the simulator on the second o2 sensor that is towards the back i wonder if it makes a difference if i place it on the first one? Also thanks i might buy one of these.
I am currently having the same issue with my setup, my setup is catless with tsudo headers, I have an o2 spacer but it’s not the design that has the cat simulator, when you ran the cat simulator it fixed your issue?
This video is soooo appreciated! Just got an 06 2.5i and I want to do some changes similar to what you've done. I want to stay non turbo but give it some bang. Keep sharing man, this is great! edit: did your check engine light come on at any point? if so what did you do to fix it? thanks
So to get this set up, -you bought the rs uel -bought the mid pipe -went to a muffler shop and get the cuts and welds done. How's the emissions? Do you think it will pass california. I need help before i go and buy the same set up as yours 😂 i dont want to mess up
IamNeil aRon yeah the rs fits just fine I've had no problem with it. When I wanted to do mine I had 3months left before doing emissions so I waited. Once I passed I give the uel headers a try. I'm not sure how Cali does emissions sorry.
jose Perez thanks man for fast reply! Do you think if i bought the rs headers, cause im currently straight piped from cat. Do you think it will fit with stock cat or i need to buy the tsudo?
IamNeil aRon No problem bro! I'm currently on you got me at a good time. Unfortunately you need the tsudo high flow cat if you skip to 2:48-59 see that bend your straight pipe won't fit, unless you ask a shop to make a bend for you on the straight pipe. Although I recommend getting the high flow cat because it's stainless better flow and sound you'd get from it.
Rexx Reviews yes they will fit with no problem only thing to keep an eye out for is they sit very close to your power steering line. So I recommend wrapping the headers so it doesn't burn your line.. only sometimes for the o2 sensors but it goes away.. another way to erase it for a good while is I disconnect the battery..
Rexx Reviews you will get a CEL light you just gotta know what o2 oxygen sensor to block off so you can trick the computer in having it think there’s an o2 sensor there
i know this is a pretty old video and topic but i just bought my own 2009 impreza hatch 2.5i na.. i bought some used cheap uel headers which look pretty much like borlas.. the thing is the uel headers i got is catless and i've seen online that without the first cat the o2 sensor will read the air/fuel wrong, turn on the CEL and mess up my gas mileage.. there is a bung for the o2 sensor at the end of the headers right before the flange.. could i cut out the cat from my original headers and solder in at the end of the flange after the o2 sensor? or does the cat have to be before the o2 sensor? Also, i've seen everywhere online that it's recomended to wrap the exhaust and get the o2 spaced out.. which i still don't know what it means... any help will be aprecciated! I just want that sweet rumble but no CEL or any other problems!
Yo bro so I have the eBay headers wrapped and tsudo high flow cat with the tsudo cat Busch but one thing that is bugging me is the the front sway bar is hitting the wrap where the three pipes are next to each other and since my subie is leaking oil it fall on the the sway bar and since it’s touching the headers the oil that falls on it then goes onto heat wrap so it soaks up and starts burning. Yeah I have a fire extinguisher in my car a prettt big one just to be extra say Incase it catches on fire. So my question is, is that is there a hump over the exhaust on the sway bar where the headers are under it
Hey buddy. Did these headers fit your Impreza fairly easily? I have the exact same year/color as yours and about to do the same. Thanks for the videos!!
Yeah they fit mine just fine I have another video about them if you have trouble. Go ahead and check them out I try to give the information on all the videos I made for it.
Been doing a lot of research on this matter, and I'm still a little confused. I have an 07 2.5i, and I would like to get UEL headers. So, with the 97-05 headers, they will bolt right up on an 07? And after the headers, I also need a high flow cat because the one cat is removed in the OEM headers, correct? Then after the cat, any cat-back exhaust for a 97-05 Impreza will work? Or could I use my stock exhaust? As for the O2 sensors, don't they both need to be after your cat because the original one was removed in the headers? Would love some clarification if possible. Really want to do this mod and want to do it right. Thanks in advance.
Hey. Watched your second video. So, would I be able to purchase the 97-05 headers and bolt them up directly to the existing '07 2.5i stock exhaust? My main goal here is to achieve the subie rumble. The headers is what unlocks that, but I want to avoid all kinds of CEL's after the install. Have you experienced any CEL's? Eventually will end up purchasing an axle-back as well. Thanks in advance again.
TheDiamondOreo yeah as you've seen it will bolt right up! So you shouldn't have a problem on that part. As long as you buy the tsudo high flow cat to bolt right up after the headers to obviously have somewhere to put the o2 sensors, you should be fine with all that. As for running it with your stock exhaust I would say it wouldn't sounds good, there's so much air now flowing. It's best to run a 2.5" exhaust piping vs stock 2.25" which is small. I'd recommend wrapping the headers to maintain heat that's running inside otherwise they cool down and the o2 sensor wont read correctly. Then that's when you have "CEL" problems, I've not yet wrapped mine and with outside temperatures at 114° my "CEL" for a o2 hasn't came back on like it did during cold days so before winter comes I'm going to wrap them.
So basically, I need the headers, a high flow cat to bolt up to the headers, and any catback exhaust for a 97-05 Impreza to bolt up to the cat? I should NOT buy an exhaust for a 06-07 Impreza, correct? If I take all of that to an exhaust shop they can do some custom fabbing to connect the catback to the cat and I should be all set? Also wrap the headers and the cat to avoid check engine lights. Thanks for the replies Jose!
TheDiamondOreo TheDiamondOreo yes you'll need the headers and high flow cat and any catback will do. If you go to 4:16 sec of the video it my mid-pipe/resonator 3" That's also a part you'd want to get a resonator 2.5" or 3".
So a year and a half later any problems. I'm going to do this setup to my friends 06 Forester and my only worry is check engine light from the O2 sensors did you have any problems with those?
Did you have any fitment issues with the header or highflow cat? I have a 07 2.5i as well and I've been wanting to achieve that rumble but have been told that even with the rs headers you still need to mod it...so I'm not sure what to do
Samuel Garcia It won't matter rumble will sound good either way! just keep an eye out for one of the power steering lines. I suggest wrapping the headers you won't need to worry about it, it's just very close to the heat of the headers.
What does the exhaust sound like when the AVLS opens up, when you're driving it hard? Also, the o2 code may be because the extension you have on the rear sensor. If yo screw it directly in, the code may go away. This is assuming there is actually a cat inside the pipe, lol.
haha! you know what, there is only one way for me to explain this to you. I had full Tsudo UEL headers, HIgh Flow cat and 2.5' cat back exhaust on my 06 2.5i and at regular RPM the car sounded like Subaru rumble then when the Vtec kicks in, it sounds like a Honda's Vtec but more aggressive with the Subaru rumble in the back round.
jose Perez did you end up fixing the o2 sensor issue? Or do you still have the check engine light for it, if so does it ever go into limp mode with that o2 censor low circuit issue?
You should be able to, but still expect some fitment issues. If you’re just trying to turbo your car, there are also up-pipes for sale that route NA headers to the turbo’s stock location.
+Steven LaSalla the Subaru is running great and I have no yet I was quoted $400 to have it tyno tuned though. I'm not sure if I want to pay that but I'm still looking around
Okay so I bought this and it get here today. Now I’m tryna figure out where my 02 sensors are going to go. Will I have to make new holes for the 02 sensors ?
Yeah no problem glad it helped getting a better idea and I know a guy had some uel headers on an older legacy it about it. I've not seen to many around or looked under on.
Austin Tatum mine is a 07 Impreza and I managed to get the uel headers from a 97- 05 Impreza to fit. It was said that uel aren't made for the 06-07 impreza's. This was just a cheaper way buying eBay uel headers for around $100 and a high flowcat for $160 from tsudo.
+Emilio Alvarado I bought my Subaru used so I'm not sure if I have stock length or if they were extended. So if you'd like to send me a picture of your O2 sensors to my email? and I could compare them to mine....jos22545472@gmail.com...
So this will bolt up to the 2006 2.5i The only thing needed is a high flow cat and anything else? The ones I ran into are for the 05, will it bolt up just fine? Also do I use the oem gaskets?
Yes it will bolt up just fine look at my other video that I put about my cracked headers I have other information if it doesn't bolt up and what I did. It's a simple fix. Yes use oem gaskets.
jose Perez Dude you seriously saved me a ton of money and frustration because I kept looking up information about it but they only stop at 2005 thank. you so much
No prob but definitely save you stock set up for emissions it's a 50/50 it'll pass running this. I really did this for the subie rumble didn't care of what other people said online on forums. I just went for it constantly got good compliments from guys in sti or wrx in person.
No I didn't. I would ask shops that tune Subarus but got the same answer " I going to charge $400 and you might not gain much." Even though I just wanted to see if a tune would fix the running rich or prevent the check engine from turning on. I also thought $400+ was too much.
The front catalytic converters that are on your stock headers basically are eliminated. When I bought my Subaru the previous owner had a straight mid pipe installed which eliminated the catalytic converter in the middle. So I basically ran no cats .
Not that I remember seeing rust when I owned it. And I drove it into some water puddles too that wrap was loose once tighten it up but like said I didn't see any.
Only reason I’m asking there has been a lot of talk on uel headers to rust with exhaust wrap but the subie community is always 50/50 on certain shit when it comes to our 2.5 liter engines lol
CyberFas yeah I remember reading information but never found anything useful, so I pulled the trigger and bought them. It all worked out good I couldn't feel the loss of power around the same time I had a new clutch installed.
CyberFas You won't lose power if you get UEL headers. What you're seeing is, if you have an aftermarket UEL header and an aftermarket EL header, the EL will give you more, just no subie rumble. But either way aftermarket headers give you a few extra HP. (from experience) 😜
Speed Limit what parts of the exhaust are you talking about or wanting to keep on with the headers? Although it won't sound good I can tell you that it's too much air flow for the stock piping. That it will sound very raspy.
Speed Limit I'm sure it's a 3" correct? Well on the video skip to 2:46 that catalytic converter or test-pipe whatever you want to call it is what you'll need. So you will then need to add more piping like I did.
If you have the UEL headers, all you need is the catalytic converter section from a 02-05 2.5rs either High Flow, OEM or Straight Pipe and it would bolt up to your stock exhaust, but IMO the system sounds better with the stock STi exhaust axle back unless you want to cut and extend the mid pipe for the STi to meet the NA cat.
will any ebay wrx 2005 uel headers work as far as bolting on to the engine work? I know you will have to custom fit it on to the rest of the exhaust. did you have to custom make a piece to fit your high flow cat? or did you not have to and was this because of the high flow cat you had? and do you need a high flow cat? what does it do to benefit the exhaust setup? I saw a another video where the guy just bought what looked like headers and a muffler and just custom did everything to fit. So can I just do the same? and as far as the 02 sensor goes he said he extended it to after the second cat to keep the computer happy. what made you go the route you did? also why did you rap your high flow cat but not the headers? sorry for all the questions. Im just trying to fully understand before I pull the trigger on buying stuff to achieve the subie rumble. i just wanna make sure i can get everything I need to achieve the rumble and still pass emissions
Ryan Coke Buying an actual WRX header required a lot of work which needed cutting and welding and, I don't have a welder. Although it does bolt up. If you do go for it. An exhaust shop in my area charged a lot of $$$ to modify. No custom work was don't to bolt the high flow cat you'll see why I needed it if you look at your stock set up. My set up was the same so you'll need the high flow cat. I went with this catalytic converter because it's stainless steel better flow and reasonably priced. The o2 sensors watch this video ruclips.net/video/6reNfUh1FGA/видео.html I explained how I ran mine. I wrapped the high flow cat because it was easier to wrap I didn't want to unbolt the headers. I first passed my emissions before I did this I suggest you do the same.✌️
@@showtimemcm no it wont its the same thing. Only thing better about having stick shift is the control of the sound perhaps on this mod...other than that your good watch my other videos if you haven't yet.. i just have a little information you might pick up on them. hope this helps!
Not really plus it really sounded good to even worry about it. I wish I could have gotten a tune on it but it cost me to much. Or the tunners said I'd gain very little unfortunately
Thanks for the reply! I have an 06 2.5i and I've been wanting to hear that subi rumble but can't afford a wrx. Can you send a link to the cat? The kne in the description leads to a page saying 404 not found. Thanks
@@brettwalls3311 www.semotors.com/tsudo-97-05-subaru-impreza-2-5rs-hi-flow-catalytic-converter-downpipe/ no problem you could also use a catalytic converter from a 200-2005 Subaru Impreza
jose Perez thanks, really appreciate it, and also I don’t really have a lift at my house but if I were to get all this do you think a shop would install it for me, and do u pass emissions with this set up?
@@silver_trek_AWD oh, i have a 2.5i automatic, apparently my turbo broke and they are replacing it, i feel like they are lying because i see no turbo or hear no turbo anywhere. my car does not go over 4000 r/pm.
jose Perez Oh k what year sti exhaust did u get? I might get the header you got from ebay, and for the exhaust there's a dude selling a 2006 sti exhaust on craigslist.
I have basically the same setup using DNA UEL header and exhaust on a 2001 Subaru Outback Limited SUS (Sedan) which has the EJ251. Had to do a small modification to the header to make it fit correctly, but it was very easy to get done.. and would definitely do it again.

Do you have an updated link to the headers?? Thanks.
Sounds great bro!
Glad you like it!
So if I wanted to buy these headers, would I HAVE to also buy a new high flow cat?
A high-flow cat from tsudo or a catalytic converter from 2000-2005 Impreza non turbo you'd only need the one after the headers.
hey, i see that these headers are listed for a 97-05 impreza but i have an 07. would there be any issues with me putting them on my car?

Jeff Boretti yes the moisture from snow and rain is held inside the wrap and it will rot much faster. happened on my mustang headers
It's stainless steel lol it won't rust
how did you get the older style headers to fit on a 07?
I'm wondering the same, I want those headers too
Will this be aight for my na 2006 2.0 impreza?
I'm not familiar with the 2.0 engine.
Do I need the high flow cat or can the header bolt on to stock cats?
Is that Exhaust JB weld?
Did you have any fitment issues with the header or highflow cat? I have a 07 2.5i as well and I've been wanting to achieve that rumble but have been told that even with the rs headers you still need to mod it...so I'm not sure what to do
Samuel Garcia no mods it all bolts right up. Only mods that had to be done were after the high flow cat.
would it matter if the car is an auto or manual trans?nothing gets in the way of anything? but thanks for the fast reply! greatly appreciated!
Samuel Garcia It won't matter rumble will sound good either way! just keep an eye out for one of the power steering lines. I suggest wrapping the headers you won't need to worry about it, it's just very close to the heat of the headers.
jose Perez ahh will do! Thanks man! Appreciate the help! Rumble coming soon!
Did you have to do any mods to fit the headers?
hey how long is that extra piece the shop welded onto the midpipe?
What does the exhaust sound like when the AVLS opens up, when you're driving it hard? Also, the o2 code may be because the extension you have on the rear sensor. If yo screw it directly in, the code may go away. This is assuming there is actually a cat inside the pipe, lol.
haha! you know what, there is only one way for me to explain this to you. I had full Tsudo UEL headers, HIgh Flow cat and 2.5' cat back exhaust on my 06 2.5i and at regular RPM the car sounded like Subaru rumble then when the Vtec kicks in, it sounds like a Honda's Vtec but more aggressive with the Subaru rumble in the back round.
Did the uel headers + new cat require a tune? Or did you just throw them on?
Keanu Coulson no tune required I just bolted them up to the subie!
jose Perez did you end up fixing the o2 sensor issue? Or do you still have the check engine light for it, if so does it ever go into limp mode with that o2 censor low circuit issue?
The only thing that needs a tune is the Intake side, but the exhaust side you're good with just bolting it on.
hey do you have that clicking noise when you put the key and you turn it
do you know what that is -- 9;53 you can hear it
josue dominguez it's the fuel pump
If you swap the subframe crossmember under the engine can you run WRX OEM headers?
You should be able to, but still expect some fitment issues. If you’re just trying to turbo your car, there are also up-pipes for sale that route NA headers to the turbo’s stock location.
Can any one find these headers ?! That don’t have 1000 dollar shipping on the actual app itself . Please send me it if so !
How is your car running Jose? Have you found anyome with open source tuning maps for your setup?
+Steven LaSalla the Subaru is running great and I have no yet I was quoted $400 to have it tyno tuned though. I'm not sure if I want to pay that but I'm still looking around
What type or mm spacers should I put
Will the 2005 UEL fit the 2006 RSi
Gotcha man and did running rich make your car run weird ?
Okay so I bought this and it get here today. Now I’m tryna figure out where my 02 sensors are going to go. Will I have to make new holes for the 02 sensors ?
You won't need to make new holes. If you go to 2:50sec on the video you can see the the o2 sensors on the high flow cat that you also have to have
Agosto Fuentes did u ever figure it out?
Do you know if the car can pass smog check if I do this to my impreza?
In California? No! Pass the sniffer, but won't pass visual.
The question is doesn’t the stock headers on 06-07 have 2 02 sensors? So where did they go?

@@silver_trek_AWD so u ran the stock headers o2 sensor to the high flow cat? Aren’t there two cats stock on our cars? I have an 07 wagon
@@ChariZmatt yes stock headers on mine came with two... The high flow cat had three sensor threaded spots so I put them to the closest ones...
@@silver_trek_AWD awesome thank you
@@silver_trek_AWD and ever get a check engine light?
Can't thank you enough it's a lot of help; Do you know if the headers will fit a Subaru legacy 2.5i 05?
Yeah no problem glad it helped getting a better idea and I know a guy had some uel headers on an older legacy it about it. I've not seen to many around or looked under on.
Will the headers work for an 07 impreza???? I’m confused if yours was an 07 or 05
Austin Tatum mine is a 07 Impreza and I managed to get the uel headers from a 97- 05 Impreza to fit. It was said that uel aren't made for the 06-07 impreza's. This was just a cheaper way buying eBay uel headers for around $100 and a high flowcat for $160 from tsudo.
did you use the o2 sensors for the headers or did you remove them?
I used them just relocated them to my tsudo high flow cat...
Great video man! Quick question, are the O2 sensors long enough to plug into the new cat?
+Emilio Alvarado I bought my Subaru used so I'm not sure if I have stock length or if they were extended. So if you'd like to send me a picture of your O2 sensors to my email? and I could compare them to mine....jos22545472@gmail.com...
So this will bolt up to the 2006 2.5i The only thing needed is a high flow cat and anything else? The ones I ran into are for the 05, will it bolt up just fine? Also do I use the oem gaskets?
Yes it will bolt up just fine look at my other video that I put about my cracked headers I have other information if it doesn't bolt up and what I did. It's a simple fix. Yes use oem gaskets.
jose Perez Dude you seriously saved me a ton of money and frustration because I kept looking up information about it but they only stop at 2005 thank. you so much
No prob but definitely save you stock set up for emissions it's a 50/50 it'll pass running this. I really did this for the subie rumble didn't care of what other people said online on forums. I just went for it constantly got good compliments from guys in sti or wrx in person.
jose Perez that’s good i essentially just want the rumble more than anything
Hey man did you have a tune in the car after u installed this setup?
No I didn't. I would ask shops that tune Subarus but got the same answer " I going to charge $400 and you might not gain much." Even though I just wanted to see if a tune would fix the running rich or prevent the check engine from turning on. I also thought $400+ was too much.
Do u have to put a new cat or will it bolt up to stock cat
The front catalytic converters that are on your stock headers basically are eliminated. When I bought my Subaru the previous owner had a straight mid pipe installed which eliminated the catalytic converter in the middle. So I basically ran no cats .
Does your Catless downpipe rust from the exhuast wrap?
Not that I remember seeing rust when I owned it. And I drove it into some water puddles too that wrap was loose once tighten it up but like said I didn't see any.
Only reason I’m asking there has been a lot of talk on uel headers to rust with exhaust wrap but the subie community is always 50/50 on certain shit when it comes to our 2.5 liter engines lol
Did you have to buy an o2 sensor extension?
scotturia I didn't. check out my other videos I explained what I did with mine
wow they’re not even fully welded
Jeez
I have the same car, color, and everything. I wanna do the UEL headers but reading through the Subaru forums don't you lose power with the UEL ?
CyberFas yeah I remember reading information but never found anything useful, so I pulled the trigger and bought them. It all worked out good I couldn't feel the loss of power around the same time I had a new clutch installed.
jose Perez ok Thanks for the info. I probably gonna do the UEL headers this summer.
Keep posting videos they're really cool..
Later!!!
CyberFas You won't lose power if you get UEL headers. What you're seeing is, if you have an aftermarket UEL header and an aftermarket EL header, the EL will give you more, just no subie rumble. But either way aftermarket headers give you a few extra HP. (from experience) 😜
ajslacker thanks a lot for the input... I wanna do this so bad this summer !!!
CyberFas Its worth it. Good luck 👍
And also did ur car smell after u installed them?
That's a good question I think mine did but went away after a few days .
In order to fit those headers could the factory exhaust fit directly?
Speed Limit what parts of the exhaust are you talking about or wanting to keep on with the headers? Although it won't sound good I can tell you that it's too much air flow for the stock piping. That it will sound very raspy.
jose Perez right now I have mid pipe exhaust it's a hks exhaust from a wrx. I don't know if I will need to add more pipe to fit the headers correctly?
Speed Limit I'm sure it's a 3" correct? Well on the video skip to 2:46 that catalytic converter or test-pipe whatever you want to call it is what you'll need. So you will then need to add more piping like I did.
If you have the UEL headers, all you need is the catalytic converter section from a 02-05 2.5rs either High Flow, OEM or Straight Pipe and it would bolt up to your stock exhaust, but IMO the system sounds better with the stock STi exhaust axle back unless you want to cut and extend the mid pipe for the STi to meet the NA cat.
yeah
Will 05 headers fit an 06
Yes the will if you are asking for 05 uel headers
@@silver_trek_AWD you’re a goat bro thank you 😎😎
great video!
+Ryan Coke thanks! I tried my best to cover what I could.
what do I need to know as far as back pressure goes?
+Ryan Coke "I would say the car wouldn't run properly and decrease in horsepower but the subie ran just fine."
will any ebay wrx 2005 uel headers work as far as bolting on to the engine work? I know you will have to custom fit it on to the rest of the exhaust. did you have to custom make a piece to fit your high flow cat? or did you not have to and was this because of the high flow cat you had? and do you need a high flow cat? what does it do to benefit the exhaust setup? I saw a another video where the guy just bought what looked like headers and a muffler and just custom did everything to fit. So can I just do the same? and as far as the 02 sensor goes he said he extended it to after the second cat to keep the computer happy. what made you go the route you did? also why did you rap your high flow cat but not the headers? sorry for all the questions. Im just trying to fully understand before I pull the trigger on buying stuff to achieve the subie rumble. i just wanna make sure i can get everything I need to achieve the rumble and still pass emissions
Ryan Coke Buying an actual WRX header required a lot of work which needed cutting and welding and, I don't have a welder. Although it does bolt up. If you do go for it. An exhaust shop in my area charged a lot of $$$ to modify. No custom work was don't to bolt the high flow cat you'll see why I needed it if you look at your stock set up. My set up was the same so you'll need the high flow cat. I went with this catalytic converter because it's stainless steel better flow and reasonably priced. The o2 sensors watch this video ruclips.net/video/6reNfUh1FGA/видео.html I explained how I ran mine. I wrapped the high flow cat because it was easier to wrap I didn't want to unbolt the headers. I first passed my emissions before I did this I suggest you do the same.✌️
Is this a 2007 Subaru Impreza 2.5i sedan automatic?
Reason why I am asking is because your car is a 2007 Subaru Impreza stick mine is automatic does it matter?
