aFe Power introduces an all new Twisted Steel Long Tube Headers and Y-Pipe Combo for the 2007-2011 Jeep Wrangler (JK) V6-3.8L. Improve your Wrangler's horsepower with these full length headers and catted y-pipe combo. In testing, this system resulted in gains up to +20horsepower and +22lbs. x ft. of torque as measured on our in house dyno. The headers are constructed of 1-5/8” 16-gauge 409 stainless steel tubing with 3/8” thick flanges to ensure a leak free seal. To eliminate flow blockage 3-to-1 formed collectors are used on the headers to decrease turbulence and increase exhaust velocity for maximum performance. The high-flowing Y-pipe is designed using 400 cell catalytic converters and 2-1/2” mandrel-bent, stainless steel tubing for optimum flow resulting in added horsepower and torque. This system is designed to fit as a combo with all components supplied for a hassle-free installation with no modifications necessary.
Long Tube Headers
3-to-1 formed collectors 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.
Heavy Duty 3/8" Flanges:
3/8" thick flanges prevent warpage to ensure a leak-free seal over the life of the vehicle.
Dual High Flow Catalytic Converters:
This system utilizes 400 CPSI (cell per square inch) catalytic converters for maximum flow.
Constructed of mandrel-bent 3" stainless steel piping to reduce back pressure and improve flow.
True Merge Collectors:
The y-pipe is designed using 2-1/2" stainless steel tubing and utilizes a mitered merge collector to eliminate dead space that can cause turbulence and hinder flow.
409 Stainless Steel Construction:
Constructed out of durable CNC mandrel bent 409 stainless steel tubing for maximum performance, corrosion resistance and strength.
High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface.
The performance header and y-pipe are designed to be a true bolt on system with no cutting or modifications required.
Note: This system is not currently CARB exempt and is not available for sale in California or for use on any vehicle registered with the California Department of Motor Vehicle.
aFe headers are engineered and manufactured in our Corona, California manufacturing facility.
