The GT-Spec stainless steel Lancer Evolution exhaust manifold has been dyno proven to gain 9hp and 7lbs torque with only a turbo back and no dyno tuning!! The power gains begin as early as 3500rpm so you get a broader increase in usable HP. Higher HP can be achieved with supporting mods and tuning. The manifold utilizes 304 stainless steel tubing with 2mm thick walls and massive .5" inch thick flanges for long lasting durability. The turbo flange and 45mm piping diameter were designed to extract the most performance and HP out of the 2003-2006 Evo's twin scroll turbo setup. The GT SPEC Evo 8 & 9 Manifold includes a one year warranty. FITMENT: Mitsubishi Evolution 8 & 9 2003-2006 with Factory Turbo
