Did the exhaust overhaul this week. PaceSetter header (2.25" out) into Flowmaster resonator/cat/Super44 muffler (2.5" out) and a GoRhino tip (3.0" out). I also sprung for a K&N air filter... $480 in parts from Auto Anything, and worth every penny. I gained a good 12-1500rpm worth of power band. IDK how much horsepower I gained (+10%?) but seat torque was imeadiatly noticeable. And that growl tho!
