According to Rustedroot, I have here a Yoshimura Pro Series-2 system that I'm looking to sell. This came with my bike ('87 VFR700F2) when I bought it but it's too loud for me (I prefer the stock exhaust which I've have recently installed). It's in OK shape (clearly, not new). I thought I'd see if there was any interest here before I throw it up on eBay. Send me a PM with an offer if you are interested. I apoligize for the sucky photo quality...cell phone camera.
Hmmm... Looks like it mounts up to the back end of the stock under engine collector. Wonder if I could make this work on the '85 vf1000r, don't think so. Mine has single outlets on each side.
The can is potentially sold. I'll update either way when the status changes. Thanks for everyone's interest!
