I bought a 2013 zx14r used, it came with VooDoo Black Shorty pipes. They sound real mean, they scream, they would be obnoxiously great at the strip but they are too loud for me commuting. They don't sound bad, its very raw and in your face but its just not for me. I really don't care if its an aftermarket or even stock exhaust. I would love to trade straight up and I we can pay each others shipping (basically you pay for small light weight and i'll pay for the bigger heavier package).
Let me know. I would prefer someone local in Tx that could ride the bike over, truck it over and we can swap out. But i'm open to anyone in CONUS.
