aFe is proud to introduce an all new Twisted Steel long tube headers/Connection Pipes combo for the 2012-2014 Jeep Grand Cherokee SRT and SRT-8 (WK2) with V8-6.4L engine. In testing, this system resulted in gains up to +35 horsepower and +55 lbs. x ft. of torque, as measured on our in house dyno. Built to eliminate extremely restricted exhaust manifolds, the performance Twisted Steel long-tube headers are constructed of 1-7/8?, 16 gauge, mandrel-bent, 304 stainless steel tubing for strength and durability. A 4-to-1 formed collector is used on the headers to decrease turbulence and increase exhaust velocity for maximum performance. The high-flowing connection pipes are designed using 48-state legal 400 cell catalytic converters and 3? mandrel-bent, 304 stainless steel tubing for optimum flow resulting in added horse power and torque. This system is designed to fit as a combo with all necessary hardware for a hassle-free installation.
Long Tube Headers 4-to-1 formed collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response. Tube lengths are optimized for true pulse control technology which improves flow and performance. The performance headers are constructed out of 16-gauge, 1-7/8" mandrel-bent 304 stainless steel tubing for unrestricted flow.
Dual High-Flow Catalytic Converters are utilized in this syatem; 400 CPSI (cell per square inch) 48-state legal catalytic converters are used for maximum flow. The connection pipes are designed using 3" 304 stainless steel mandrel-bent tubing for optimum flow and high resistance to corrosion. High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface.
This system is designed to fit as a combo with all necessary hardware, making it a true bolt on system with no cutting or modifications required. All aFe headers are engineered and manufactured in our Corona, California manufacturing facility.
