Just curious. Why ACM vs 4 pipe? I've heard the drone is pretty bad with the ACM mod and not worth it for the slight volume increase. I've also read the 4pipe sound quality is better than ACM.

^ are you running the ACM mod? I've read dozens of posts that say the ACM mod drones. My Megan drones like crazy from 1,800-2,200.

I have the ACM but I also have had most of the other good exhausts before as well. Truthfuly even the stock has a very small drone around 2k rpm but this is not any worse than stock in that department. The Megan exhaust and Meisterschaft do drone. ACM doesn't or if it does it's like stock exhaust

ACM exhaust mod has zero drone. Aside from all the cars we've done since 2010, I ran test pipes + acm exhaust mod for about 4 years daily and no drone whatsoever.
