â€¢Incorporates a catalytic converter
â€¢Outlets connect directly to OE exhaust
â€¢Heavy-duty flanges and OE-style gaskets are used to maintain a leak-free seal
â€¢Added an extra +2horsepower and +7 lbs. x ft. of torque as verified by our in house dyno (dyno results from "street" version 48-46217-YC)
aFe is proud to introduce an all new â€œRaceâ€ Twisted Steel long tube headers/Connection Pipes combo for the 2000-2006 Jeep Wrangler (TJ/LJ) with I6-4.0L engine. Designed to replace the extremely restrictive exhaust manifold, the performance Twisted Steel long-tube header is constructed of 1-1/2â€, 14 gauge, mandrel-bent, stainless steel tubing for strength and durability. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability on and off the trails. In testing, this system resulted in gains up to +2 horsepower and +7 lbs. x ft. of torque, as measured on our in-house dyno. The header comes with a 1/2" thick laser-cut head flange that is designed to match the head port for a leak-free seal. Formed collectors are used on the header to decrease turbulence and increase exhaust velocity for maximum performance. The high-flowing Connection Pipe is designed using 2-1/2â€ mandrel-bent tubing for optimum flow resulting in added horsepower and torque. This system is designed to fit as a combo with all necessary hardware for a hassle-free installation.
Stainless Steel Construction:
This system is constructed of durable mandrel bent stainless steel tubing for maximum performance, corrosion resistance and strength, eliminating cracking.
Factory Mounting Locations:
Utilizes factory mounting locations making it a true bolt-on system and includes all necessary hardware for a hassle-free installation.
Utilize formed collectors to decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response.
Optimized Tube Lengths:
Tube lengths are optimized for true pulse control technology which improves flow and performance.
1/2" Laser-Cut Flanges:
These headers come with 1/2" thick laser-cut head flanges and gaskets that are designed to match the head port for a leak-free seal.
