I have two Scorpion mufflers (HA76SSO). They are stainless, oval shaped. These are brand new... here's the catch. Zero, none, zilch mounting hardware. I received them this way from cyclegear and they tried for two weeks to find/acquire the hardware. No luck. Rather than RMA they let me keep em for the price of shipping but I don't want to fool with trying to make them work. If you've already got some after market exhaust mid pipes you might be able to use these. They are oval shaped so keep that in mind. I'll sell em separately.
If one were handy or resourceful you could either make some mounting hardware or since the shape looks like every other oval can just search ebay for them or contact any other exhaust manufacture for theirs. Great deal for someone wanting to put a little work into it.
