Our very first racing pipe, made for the Menace, Phantom and Malice engines. Quality and performance are unmatched. For best results, use a 44 tooth sprocket. The power band comes on at around 8,000 rpm and pulls past 14,000 rpm. While this pipe works fine for non ported engines, it pulls HARD on engines that have been ported with higher exhaust timing.
It comes complete with slip-fit header, branded silencer and hardware. Secure the stinger mount to bike frame very well using your own solution. For best fit, use with felt faker or any gas frame style. Use bottom bracket at least 127mm wide for best fit.
