I've got an old Piorun Eclipse that really needs something rear exhaust to work right. I recently had it set up with a YS .91 FZ but balance and vibration issues plagued that combo. I got it down to slightly over 8 lbs. with the YS. I think It would be a hoot with the MVVS .91 rear exhaust combo. Where in the US is the best place to get the MVVS with header and pipe?
