EPA Noise Test
Wondering if anyone has had any experience with this?
I've got an Akra Evo setup on my e92 and received the letter just today.
Either the spotter is retarded or something, because M3s do not emit the same sounds as a 320i, and I'm sure Akra ain't much louder than stock.
Not to mention, my previous Z4M with ACS exhaust was actually louder and it never caused an issue.
