Went for an hour long ride today to try them out and man what a difference! These coupled with a driven +1 front sprocket made all the difference. I. Wanted to give a shout out to Nate from MotorcycleGear.com for really hooking me up. He went out of his way to get me the exhaust at a good price and quickly. Just wanted to say thanks. I highly recommend these mods if your looking for better performance and sound.
