i'm doing some tweaking on my 4th gen max.

if you've replaced your 5th gen muffler with an aftermarket part, sell me your oem.

i want to see if the variable backpressure will help me out now that i have a y-pipe to a 3" straight b-pipe. the stillen exhaust make my car sound like it has a jake brake!
