The Turbo XS Racepipe is designed for the Evolution 8 only as it has no built in O2 bung. Though, if you wanted you could easily add a bung to this 304 stainless steel cat delete pipe and run it in your 06 Evolution 9. The Turbo XS racepipe will connect to any stock or aftermarket exhaust that connects to the stock location cat pipe.
Note: If modified this will fit 06 Evolution 9
Part Number: EVO8-RP
