Another absolutely amazing install video. Man hands down you have the greatest install video channel on RUclips!!
Thanks brother, I appreciate that!
I've been eye balling this stage 2 kit for almost a year, with that exact exhaust combo! Can't wait for the next video!
Tip: if it's not available on their website as a package, email them and request it, which is what I had to do. It saves money over buying the items individually.
I'm still going to have a shop do it lol but God Damm this guy is the best at DIYs. Thank you so much man. All other subie guys talk the first half hour to an hour and install not as descriptive as you. Boost & shutter gets to the point. I did use ur Iag aos install and installed mine. Thank you man.
Thanks man, it wasn't all that bad, but yeah also not the easiest. The AOS install was easier for me.
@@akqjtn Maybe I'll give it a try and see what happens
I did the same MAP Stage 2 package. I removed the intake for a few months because of heat concerns. I was seeing 170F IATs when sitting in traffic etc. I just reinstalled the intake this weekend after putting some DEI heat reflecting material on the intake. Now I see IAT's that are comparable to the stock intake. Have been running this setup for just over two years and it's great.
Did you run stock or aftermarket injectors and what year was your STI?
@@hoodyFPS I'm back on the intake and downpipe now. I've added an equal length manifold and exhaust. Stock injectors and fuel pump. A pro-tune from jazTUNING got the car working flawlessly. I have injectors and a pump ready for the upgraded turbo shortly. You don't need injectors and a pump on the stock turbo on 91, or 93.
@@ChrisHale0629 you do need injectors if you are running a aftermarket intake and downpipe. You will max out your fuel duty cycle extremely fast. Also get a box and it will drastically change your temp. With a box you should be at ambient or a few degrees higher.
@@ChrisHale0629did you not throw the P0420 code?
@@frankfly1368 eventually I did. I've replaced the AP with an EMtron KV8 and the downpipe with a Cobb.
Been enjoying Stage 2 for a few weeks now, this is my install how-to. Let me know what you think!
@Boost&Shutter you for got to mention before you go ahead and start taking your down pipe make sire you buy extra turbo studs just for safety sometime they come out stripped out or tend to break. Good video and great explanation
That's actually a very good point. Thanks for sharing 👍
Hey! Your STI is coming along nicely! Any input into needing fueling upgrades with the downpipe + intake combo on VA chassis EJs? I guess MAPerformance has their own tune to account for that. Curious if you're planning on fueling upgrades in the future.
Thanks! You hit the nail on the head, the OTS tune is pretty conservative so fueling upgrades are not necessary. It's a nice step and you get a decent upgrade while you get more parts to push more power (like fueling upgrades), which is what Im doing.
Great video, can't wait to hear the sound comparison. Maybe it'll convince me enough to get an aftermarket downpipe
Your content is amazing, as always. Take care!
Thanks! Review of this dropping today, check it out.
Pro video! I watched your speaker install before this, awesome vids!
Glad you find them useful. Thanks for the comment!
Did you go with the high flow cat or did you get the GESI cat? I’m on the fence between the 2.
A great, detailed how to video! ThankU.
How safe is it to do this with a tune ? Really would like too but keep hearing stories about blown engine 😟
Can you explain to me why my tuner says I can ONLY get the Cobb down pipe on my 2021? I don’t understand other than they said it’s the only one I can get with CEL’s and they even said I may need 2 cats.
I’ve got the fix, anyone running a 19-21 that wants to run the DP, hit me up and I’ll share the secret sauce. Installed mine and I’m CEL free 🤙🏻
One thing I don't like about the turbo snuggie and wraps is that they fall apart overtime. If thr turbo oil feed line get ruptured, oil soaks into the material and will cause a fire. I always recommend high temp ceramic coating like Jet-Hot or SWAIN Tech over the wraps
Did you get a P0420 code? I can’t get rid of it
Question. Would a turbo blanket alone work well enough or is it important to also get the heat shield in conjunction with it
Man, I bet you have a lot of battle scars dealing with taking off the stock down pipe!
Haha, my biggest injury was walking barefoot in the garage and catching the sharp edge of the heat shield with my toes. I must have lost a pint of blood 🤣
Initiative as always
Thanks bro
Hey man great video. I have a 2018 sti and want to install Downpipe with a intake and I heard that it a no go for 2018 models. Do I need to change the fuel pump and injectors for it to work properly?
My tuner told me I can run the intake dp combo in my Sti if I upgrade the fuel pump and fuel pressure regulator.
Just curious, where does the front o2 sensor plug into after you install the MAP down pipe?
Do you get a CEL with the high flow downpipe on your 2020 STi? 2019+ STis have issues with downpipes from what I have gathered. Thank you
I am still searching the internet on this issue. No one talks about it. I have a 21 STI. I installed an invidia DP with high flow cat. I had a CEL that couldn't be tuned out and with the Cobb Greenspeed movement we are SOL. 2019+ STIs are a tier 3 emissions vehicle meaning the ECU is much more sensitive towards emissions. I've been speaking with many tuning shops and they're aware of this issue. They've recommended to me to purchase a Cobb Gesi cat downpipe. Cobb on their website has removed the VA chassis from the fitment list. The 09+ gesi DP fits and works. There is still a possibility to get a CEL from time to time. But you can clear it and run it. Right now this is the only known part solution for 2019+ sti downpipe. Big price at $1000. Curious as to how others are running DPs without CELs or if they're not sharing that this would be the result.
@@gavinbushore4203 Thanks for the reply man! Unfortunately the COBB GESI does throw a code. However after some digging around and a few called, Grimmspeed just dropped there version 2 downpipe a few days ago. I was told this downpipe should not throw a code and they advertise the cat to have "OEM level emissions". When I spoke to them it was before they released the downpipe officially, so I would give them a call to confirm. Their customer support is great!
How do you end up choosing the MAPerformance dp?
Where do you live? Your 2020 STI is way rustier than my 2019.

How bad of an idea do you think it would be to get the redesigned 22 sti right when it comes out?
I do have a video covering that, but in general you don't want to be the guinea pig. I'm sure on paper it will be very tempting though, but the current Gen has that old-school feel that is disappearing more every year. I guess we will see in a couple of days on the reveal.
My intake bracket bolts snapped when I undid them so now I cannot attach the bracket. I’m also unable to reach the MAF sensor unless I install it the other way around, since I didn’t know I needed the extension. Right now I have it just hanging by the attachment point. What should I do? Get a shop to drill it or find a way to 3M tape the bracket on?
Detailed in your let me start liking ur video
What you guys recommend, MaPerformance DP Or Grimmspeed
very informative video, nice.
Good stuff
Biggest bottleneck is the tiny turbo, not the downpipe. Evos had bigger hotsides.
this is why i went with the fa20 sooo much easier and you dont need to upgrade the fueling for stage 2+
Keyword "tune" if anyone installs this without a tune, you will not gain any performance.
I want a downpipe for my 21 sti but everyone tells my I’ll have a chance of a cel
