Hello! I recently acquired an E90 N55 from a dealer near me but I found out that it was straight piped, but I think it just sounds cheaply done in terms of sound quality. I have a catless downpipe waiting to be installed but I was wondering about any tips on basic modifications? I love the loudness and tbh the loudest I can get the car the better in my eyes. I’m new(ish) here in the forum so any N55 advice for modifications would be greatly appreciated!
