Description

The new Twisted Steel performance header from aFe Power is redefining the header industry with new pulse control technology. aFe engineers have designed this header using optimum tube lengths and mitered collectors for maximum flow and velocity for power delivery across the entire power band. Combine with a large 1/2" thick head flange and 14-gauge 409 stainless steel tubing, you have a header that is strong and powerful. Twisted Steel headers are 100-percent bolt-on with no modifications necessary and are proudly engineered and built in Corona, CA.

Product Overview

aFe Power’s new Twisted Steel header delivers more horsepower and torque while outflowing the factory exhaust manifold. The header is constructed of 14-gauge 409 SS tubing with a 1/2” thick head flange to ensure a leak free seal. To eliminate dead space that can cause turbulence and hindering flow that formed collectors are prone to produce, a true merged collector and optimized tube lengths are used for true pulse control technology improving flow and performance. 100% hand TIG-welded construction ensures optimal 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. All components are supplied for a hassle-free installation with no modifications necessary.
