The sound that a flowmaster makes varies greatly with what/how many bends are in the pipe. I have a thorley beader, no cat and a 40 series flowy. When I had 2" pipe the flowmaster was behind my seat and the tailpipe exited in fron of my driver rear tire it was borderline throaty. Now that I have 2 1/4" and the muffler is right in front of the axle and exits behind the rear tire out the side it sounds like a very pissed off chainsaw. Its one ricer sounding bastid. Im going to change the whole exhaust this summer so Ill live with it for now. Ill still replace it with a flowmaster but Ill use a deltaflow most likely.
