Hi everyone. I have the opportunity to purchase a brand new E90 M3 exhaust for $300. The exhaust only had 7 Kms. on it when it was removed. I purchased an M3 rep front bumper and was planning to purchase either the M3 rep rear bumper or the M tech 2 rear bumper. My questions are...

1) Is it worth all the fabricating to make it fit on a 335I?
2) Will there be any gains over the stock 335I exhaust?
3) How does the M3 exhaust compare to the 335I BMW performance exhaust regarding weight, sound and performance gains?

Any input is greatly appreciated!

Don't do it, stock M3 exhaust won't do anything for you.

Get a proper quad pipes 335i muffler if you want one.

Or the BMW PE

Or just do a muffler delete.

Thank you for the advice! I had a feeling that would be the case but needed confirmation. Hopefully I can find a good secondhand BMW performance exhaust.

not worth the effort or money at all.

delete your secondary cats and PE mod to your muffler. or get a catless downpipe and youll be happy
