I have a Scorpion RP-1 GP exhaust that I had on my 2014 Blade which I no longer required since fitting my SC Project, so I decided to fit it to my brothers 2010. Rather see it going to good use instead of it collecting dust. First made a spacer from a piece of 60mm diameter aluminium. Made it a tight fit, inside diameter just under 50mm. Welded on a bung to accept a wide band o2 sensor to work with the Dynojet auto tune. (Excuse the welding, first time welding stainless steel and didn’t have enough gas to experiment. Let’s just say it’s strong enough.) Looking better on his bike than it did on mine.
