The 2006+ dual exhaust Impalas really have 3 mufflers, ofcours 2 on the end but theres one directly under ur car. i had that muffler cut off and put a straight pipe instead. It allows it to breath more, more power, more punch(tourqe), Flow masters as well, and sum chrome tips.
is it loud in the cab?
