Are you acting stupid or just wasting your time. Go 2.25.

. The muffler delete sounds good on AT. When i did my muffler delete i know i could not fit the CYba 4" tips on them because they were the same size witch was 2.25 so maybe go 2.5 so you could get the tips to fit.

It's probably because you're running rich and backfiring. This is pretty typical for the 335i, especially on a cold start.

Have you removed any cats?

Here's my post from another thread...take it seriously!

"Pay for the right thing the first time, you will only cry once." I learned my lesson by going from muffler delete + tips (200) -> TopSpeed Experiment (600) -> AMS exhaust (1300)...it makes so much sense to just pay for the best option first time around.

Learn from my mistake!
