CATLESS DOWNPIPE WITH THE POPS TUNE WILL IT SOUND GOOD?
DOES IT COME AS LOUD AS BMW M2 OR M4 WITH THE CATLESS DOWNPIPE?
Someone I know has an M240i (same motor) with decatted downpipe running on BM3 tune (aggressive burble) and I find it annoyingly loud. I believe he's still running stock muffler, too.

Catless with factory catback pops much louder than most BMW's. I'm running the magnaflow with muffler on normal side and test pipe on sport side with a 4.5" catless downpipe, the pops make ears ring at 10' it's special kind of loud lol; really has to be heard in person to comprehend how loud it is. Also tuned so that may contribute to volume of my setup with the way these motors handle charged air without diverter valves (anti-laggish manner).

I never got around to posting a clip of the muffler delete, so here you go. Hope this helps you with your decision.

Are you on stock downpipe and stock tune? Just rear muffler delete? Also did you reinstall the active exhaust module?
