Well since I decided not to buy a new bike I decided to modify and maintenance mine. The Alley Kat all stainless mufflers that I found new old stock from 2008 are amazing. By far the best set out of the ones I had before - Cobra Six-2-Six and TBR Comp S. The O2 eliminators improve the low speed low load driveability. The black ceramic Torq Loopz installed perfectly without any issues. And my last maintenance item was accomplished which was the factory air filter change. Was going to plug the PAIR system vent in airbox but decided not to since I was not sure if that would set a light code. Plugging it would not improve performance but would stop some exhaust popping by blocking the air supply from being pumped into the exhaust when under light load - closed loop. Very happy camper with my SPORTY F6B. It now has a different attitude.
