aFe Twisted Steel Header SS-409 HDR Jeep Wrangler JK 07-11 V6 3.8L

aFe Power?s new ?Race Only? Twisted Steel Headers deliver 6 hp and 6 lbs. x ft. torque while outflowing the factory exhaust manifolds. The headers are constructed of 1-1/2? 14-gauge 409 stainless steel tubing with 3/8? thick flanges to ensure a leak free seal. To eliminate dead space that can cause turbulence and hinder flow that formed collectors are prone to produce, true mitered merge collectors and optimized tube lengths are used for true pulse control technology improving flow and performance. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. All components are supplied for a hassle-free installation with no modifications necessary.
