dual setup on 328 with performance exhaust - BMW 3-Series (E90 E92) Forum

KayMo · 09-22-2012, 04:23 PM

i have a 328i lci and im thinking of changing the exhaust setup to 335 setup but i have performance exhaust and i really dont wanna lose the nice sound because of cuttings that has to be done to the pipes...so my question is,has anybody done this with performance exhaust and how is the result going to be?

it has been done. Can't remember the thread name. apparently the member who did it said it changed the exhaust note. Toned it down, but that could be subjective. I am going to sort of do the same with a stock muffler. M3 quads. One of us will find out sooner or later.

i would do it to stock muffler no problem but since i have the performance exhaust i am not sure what to do here,i wont be happy if it makes the tone go down,hopefully i can find out about this soon.

where did you get it done any may i also ask how much did it cost?
also if you have any video from the exhaust that would be great.

I have a custom system now but I bought a set of stock mid pipes that I am going to use with my stock system. I am also going to have my stock muffler turned into quads. This is all in prep for getting catless primaries. The stock muffler and pipes are needed to get keep torque at low rpms. I actually lost power with a custom system.

I had exhaust work done at evolution auto performance. If the three of us are looking to get work done, we could all go together one day to a shop that does decent welding. Evolution does tig welding.

Looks great. Thanks for sharing. Which tips did you use? Do they tig or mig weld there and how much was it?

Also. I would suggest a v-band set up if you take out second cats. That way you can throw them back on when needed with ease. You won't have to worry about air care for a few years but eventually you will.

Yupp I was the one that did this first

I'm glad it was an inspiration!

Well, to tell you the truth, the sound decreased a bit after the conversion but it got WAY louder with the cat delete. Get one, you won't be disappointed at all. Your car looks awesome btw.

good to know that it gets louder but does it still have the popping sound?
thanks

Haha if you think you're gonna lose the pops, you got another thing coming.
You shouldn't worry about pops, you'll be hearing them... A LOT.
When I say A LOT, it means, excessively... More than Stock PE.

(That is.. due to the cat delete of course...)
