AFE Twisted Steel Long Tube Header & Connection Pipes Street Series Dodge Challenger SRT-8 2011-2014 V8-6.4L HEMI

aFe is proud to introduce an all new Twisted Steel long tube catted headers/Connection Pipes combo for the 2011-2014 Dodge Challenger SRT-8 with V8-6.4L engine. "Improve your Challengers horsepower" with these full length headers and connection pipes. In testing, this system resulted in gains up to +19 horsepower and +17 lbs. x ft. of torque, as measured on our in-house dyno. Designed to replace the extremely restrictive exhaust manifold, 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 200 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.

304 Stainless Steel Construction:
This system is constructed of durable mandrel bent 304 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.

Headers:
Formed Collectors:
4-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.

3/8" Laser-Cut Flanges:
These headers come with 3/8" thick laser-cut head flanges and gaskets that are designed to match the head port for a leak-free seal.

Connection Pipes:
Dual High-Flow Catalytic Converters:
This system utilizes a 200 CPSI (cell per square inch) catalytic converters for maximum flow.

Mandrel-Bent Tubing:
The performance connection-pipes are constructed of durable 3" mandrel bent, 304 stainless steel and connect directly to the OE or aFe exhaust.
