I have an '06 330i and this video inspired me to get the muffler/secondary cat delete that same week. It's been about a year since I've done it and couldnt be happier. It's not too loud, but has just enough noise to make it sporty 👍 and the fact that it pops without a tune is just the cherry on top 🔥
Dude those backfires 😍😍😍 I’ve seen a couple guys with muffler and secondary cat deletes and it sounds no where near as good as yours!!! Did the muffler shop do anything special because those pops are just so crazy
Bro how long has the pipe been worn when u took the vid? I just deleted my muffler and it pops but urs a lil more louder and longer but maybe is because u alr worn the pipes a bit
Rogers Finch primaries. But the are inside of the headers so you would need new headers. Removing secondary cats is faster and cheaper. But if you remove both then it's and insane amount of backfire
hello I have a 330xi e90 2006 until now I have it with muffler delete if I remove the cat does it become annoying for the day to day? I wonder why I am on the road a lot also thanks and greetings good video!
That sounds so sick dude! Would just a secondary cat delete sound good or would you advise pairing it with the muffler delete? I don't want my car to be too loud.
delete your secondary cats and install a borla or magnaflow muffler in place of your stock one. check out your video if you want to hear what that sounds like.
@Gavin Pawluk I currently have a muffler delete and I’m abt to go and get my secondary’s removed. From what ive heard most ppl go w muffler and secondary or just straight pipe it from the primary cats back. I’d say go to a shop and remove the secondary’s and if it isn’t loud or aggressive enough then remove the resonator
How everybody, I was wondering how much of a downpipe would the muffler delete + the resonator delete, maybe 20% of a downpipe of freeing power? Or what would you say that would that is the equivalent to a downpipe?, I already know that the muffler is restrictive and also is the downpipe, and to a certain lesser degree the resonator, you see I don’t want to take out my downpipe and put a catless downpipe in, like everyone else does out there, my option to a downpipe would be a resonator plus muffler delete, the porcentagem to a downpipe in freeing power of the exhaust system, that sound is even better with a muffler and a resonator delete on a bmw 330i or 320i, because it’s less raspy to me.
Love the vid! I have a 2011 bmw 328 with a muffler delete and I like the tone.. if I do secondary cat delete will it make it any louder? I don’t want it to be loud I just want more pops... thanks!
Hi, i have a 525i 2005 with resonator delete only and still have the cats, what should i do to get burbles or pops?? :( I keep searching a good answer cause a lot of people said that you need a repro o something and others say a dif thing, pls help, i want my car to pop insanely
Hi, nice sound you have there. I have a 330i as well and would like to do a muffler delete. My concern is about the low end rpm which I'm in mostly due to city drives. Do you lose any power or pace? Thanks!
How long did it take for your set up to break in? I recently got my secondaries done recently (still have my resonator) and to be honest the noise sounds about the same apart from the deeper exhaust note. I also thought my car would pop and burble a lot more but again, feels kinda the same when I just had a muffler delete
@@frankielatargia3491 yeah, I figured. My car does pop and burble, but pretty much exclusively on the down shifts. I don't really wanna take my resonator out because I have the strong feeling that I'll want to put it back on shortly after. Definitely satisfied with what I have now.
Not true, the pops are caused by unburned fuel exploding. The cats are what are supposed to burn off those fuels, hence without cats you get pop. Maintaining the res will actually keep the tone deeper. Take out the res and your straight rice
How is your piping set up? I want to do this to my 06 330i. Do you neck down to 1 pipe after the manifolds, back to 2 for the resonator, then back down to one the rest of the way, or 2 pipes up to the resonator off each manifold? So I know how to explain it to the muffler shop. Thanks!
So for the cats, literally just cut out the two cats and put in two pipes to fill in that gap. And for the muffler, again, just cut it off and welded one pipe out the bumper and welded tips to the end of it
Would you say it got louder after the secondary cat delete? I notice it crackles/pops a lot more but the note sounds almost the same on camera. Getting a Muffler delete done sometime this week, curious if I should just remove both.
TGSN _ so when it's in park the revs sound pretty much the exact same as just the muffler delete. But when it's under load and your driving it does sound different. A bit louder and deeper rumble and tone. Honestly would recommend getting it done if your going to get the muffler delete anyway. It's a good compliment to the sound.
First things first just wanted to say the thing sounds awesome man xD. Secondly what did the muffler shop do? (what size pipes, what tips, etc) I have a 2010 328i and would love for it to sound like yours :)
Jarrod Hickman so they welded 2.5inch pipes to replace the muffler and secondary cats, the tips I got for like JEG's or something for like $60 and they welded them on for me.
Yes there is a list in low end torque, it smells bad and will sound horrible with a resonator delete. That being said you will need a tune to tie in the deletes
I currently have muffler delete on my e92, and I can definitely feel there are loss of torque without the muffler. I'm thinking about doing second cat delete next. Do you know if second cat delete makes the car lose more torque?
Removing a muffler and/or cats actually increases hp and torque because you’re letting the exhaust flow better, which is also better for the engine. You could gain probably up to 20-30 hp and 20-30 ft-lbs of torque by doing the car delete
I have a 2011 bmw 328i e90 automatic and I currently have a muffler/resonator delete if I remove the cats as well will it make the same amount of pops and crackles as in the video?
i want my 325i to sound nice and loud but as a daily driver but i don’t know anything about that. what do i do to my car? what is the best thing i can do to it? can u help?
I'm thinking catless headers, high flow cats on the front pipe section, custom piping for the midpipes with resonators, and stock muffler. Idk this car well, I gather I'd get the sound I want(medium loud/deep tone) I dont like cheater extenders on the o2 tho. Will need to do more research. Do the shark injector reflash have a fix for it?
Hey I know I’m late to the video but I was wondering how many codes it throws. These cars have lots of sensors. I’m looking at doing this so does it throw codes Bc you did this etc?
It didn't throw any codes from the muffler delete or the cat delete. When you start messing with the cats and O2 sensors is when it starts throwing codes and errors
Dudeee, i cut the secondary pipe, mid pipe and catback pipe. Sounds super terrible and i need to put on the resonator back ASAP 💆🏼♂️But honestly after i cut the secondary pipe, more burbles 😍 nice video btw 👍🏼
Getting just a muffler delete on e90 328i, with that being said does having a 330i sound any different compared to the 328i with a muffler delete? Or are they about the same?
hey brother, i got the exact same bmw as you and I just got my secondary cats taken off like 3 hours ago but it doesn't pop or burble anywhere near as much as yours does and i was in sport mode. any ideas as to why??
Hey dude! Hmm im not sure to be honest. To make mine pop the way it does there's like a few tricks I guess you can call them to make it sound that way. The sweet spot is around like 3.5k on the RPM range and I kinda tap. Maybe I'll make a Video on it if you'd like.
Same i got the same thing done to mines, my second day now but its been really cold outside where i live so idk if that has anything to do with it? Or does it have sorta of a break in period if that makes any sense idk lol

Edward Contreras no reason a cat could be bad for the car. Its for emmison purposes mainly. And secondary cat has no sensors so no check engine because of that
Deleting resonator and muffler will be loud but if you really want pops, the cats are what prevent it so removing the cats would give you the most pops and remove all three for most pops and volume

@bimmerboii did have any droning noise from either setup at cruising speed?
how would it sound on a manual 330i I'm thinking about doing that on my car ..would i be able to do the smoke check though?
For the cat delete did you take out the stock cats and put cat less down pipes or you gutted the cats
Where’d you get those rear diffusers? Got the link?
Dude those backfires 😍😍😍 I’ve seen a couple guys with muffler and secondary cat deletes and it sounds no where near as good as yours!!! Did the muffler shop do anything special because those pops are just so crazy

You kept the resonator?
Do you still have the resonator installed or is that deleted too?
Hope all is well bro god bless you ❤️🙏
Hey, love the video. The car sounds amazing! I have a 2006 BMW 325i. If I get a muffler delete should it backfire as much as yours?
Rogers Finch not that much with just a muffler delete. You would need a primary or secondary cat delete to have alot of pops
slerp645 which would give me more pops, primary or secondary cats?
Rogers Finch primaries. But the are inside of the headers so you would need new headers. Removing secondary cats is faster and cheaper. But if you remove both then it's and insane amount of backfire

That sounds so sick dude! Would just a secondary cat delete sound good or would you advise pairing it with the muffler delete? I don't want my car to be too loud.
delete your secondary cats and install a borla or magnaflow muffler in place of your stock one. check out your video if you want to hear what that sounds like.
Honestly if you want a subtle performance sound just replace the stock muffler with a magnaflow
Best Vids what did you end up doing?
the car is stock other than the muffler delete an secondary car delete?
perfect video. you're the man.
Thank you. Appreciate it!
BIMMER BOII question do you see any difference in HP?
Does O2 sensor code comes out ( check engine light)? After taking the secondary cats off?
Did it give u the check engine light?
Sick ass headlights bro, where you get em? I can’t find any nice ones for my 2009 328i
Ik this is an old comment but they’re just red tint cutouts for the reverse lights you can buy on amazon, those are stock pre lci tails
How much was the muffler delete for you?
