Help with e92 m3
I wanted to learn how to work on my car so I took the rear end of my exhaust off and reinstalled it (since I'm planning on getting a new exhaust in the future). And when I put it back on it is much louder than before. It sounds really good to be honest, but there's a lot of drone. I think the sound is coming from one of the cats, but I'm confused because the pipe is connected and clamped down. Should I be worried?
