Hey guys
I have inquired about a cat back exhaust from xflow/Xcede for my 135i, and wondered if anyone has one on their 135i? Any feedback will be appreciated, thanks.
Thanks dude, my other option to run the BMW perf zorst without the mid box resonator, heard there is no drone or its minimal... but a custom exhaust could be worth it, pricing is about the same.
sounded awesome, the dyno yielded good results.
i had a claim on my car en had to take it for BMW approval
didnt wanna take a chance loosing my MP for DP's.
