2020 330i catless downpipe?
Hey all, I just picked up a 2020 330i and absolutely love it!
I wanted to keep the stock exhaust so I can keep the valves, I was wondering how much of a difference getting a catless downpipe would alter the exhaust notes, would it pop and crackle more? Also throwing a check engine light is a concern! Please and thank you! |
