Looks great and sounds great

Comments On Sep 21, 2015:The FMF 4.1 aluminum exhaust system fit perfectly, looks excellent, and it sounds great. Along with an ECU remap, it certainly gave the bike more power, and deleting the left muffler probably helped a bit too. The UFO side panel fits perfectly as well and the bike looks as though it came from the factory with single exhaust now.
