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!

yes it will make more sound, pops and crackles.

Yes you will get a CEL, you need bootmod3 to hide the code
