"Hey guys I just picked up my new M4 but want a little more engine noise. What do you guys recommend?
A: Don't even waste your time with a drop in filter or an exhaust. Alpine just released an amp that claims at least 20% increase in BMW's active sound. Also try putting tweeters in two of the four exhaust tips since artificial sound is way better than the real thing."
