I must say it is a whole new monster with a pipe on there. I'm going to retune it for riding with a pipe and i have the tune for header only saved and i will use that at the track. It cost me $378 shipped for the can, clamp, and springs. Its extremely quiet now as well i cant even hear the bike when i'm cruising down the road. It sounds alright so i guess i'll just keep this system.
