Don’t do muffler delete. Sounds good but has a lot drone. I mean a lot. I did it and I even add small muffler and j pipe to limit the drone but I put muffler back after two weeks. Now has fi valve exhaust on the car. Perfect setup for a daily drive. My ig is @joseph.m240i let me know if you have any questions. I saw there’s people saying how good it sounds and no drone. But trust me, go get a aftermarket exhaust system don’t do only the muffler delete.
