Hi all,
My car (535i) currently has an M5 exhaust, but, of course, it is not as loud as I want it to be. So quiet that I can almost never hear it inside the car (I had to turn back on ASD because it was so quiet).
I’m thinking that upgraded downpipes would definitely make the car louder and more enjoyable.
But here is the problem, I’m not sure what I could get that gives me a sound increase while passing emissions.
I live in VA if that is any help. I guess they do emissions differently other than just reading codes.
Please shoot with some suggestions!
