Twisted Steel Header

This system produced gains of up to +20 HP and +23 lbs. x Ft. TQ., as measured on our in-house dyno.This system is constructed of 1-5/8 IN mandrel-bent 304 stainless steel tubing for maximum strength and durability. This coating combination reduces the outside surface temperature of headers and reduces engine compartment temperatures. Factory style laser cut machined mild steel flanges are used used for a secure leak-free seal. These headers retain your stock catalytic converters and are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation. Mitered collectors decrease turbulence and increase exhaust velocity. The result is increased horsepower, torque and improved throttle response. A Machined ball flange ensures a leak-free seal over the life of the vehicle. 100% MIG-Welded for race-proven strength and durability

Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

aFe Twisted Steel headers are constructed of 409 stainless steel tubing with thick, CNC-machined flanges to ensure a leak-free seal. They incorporate a merge collector design, reducing the turbulence that occurs when using the traditional form collector-style designs. The performance gains are obvious when coupled with a high-flow Y-pipe. The aFe headers feature a tuned length primary that is out-flowing the stock manifolds by as much as 46 percent.
