This is the all-new 'Super Tourer' expansion chamber exhaust for Casa PerformanceSST265 motors.The Touring version of the famous SSR265 Scuderia is the SST265 Touring set-up, and that is designed to work with either a box Clubman Plus exhaust, or for those who want more speed and power, this expansion chamber, which is the result of months and months of endless development.The idea is to offer performance closer to a ScuderiaSSR265 motor, by simply changing the exhaust, making the SST265 all things to all men. The performance was actually more than we'd expected and you'll be seeing 40bhp+ with this exhaust fitted to an SST265 with a 34mm Dell'Orto carb. "Whats it like out on the road?" Well, let's just say that this is no slouch. With performance not light years away from a Scuderia SSR265, an SST265 with this exhaust is a whole lot of fun to use!
