      Description

      More Horsepower And Torque. Does your GT Mustang spend equal time on the street, strip and track? Then you really need to replace those restrictive cast factory manifolds with a set of Stainless Power Long Tube Headers for the power you need to defeat your competition. Stainless Power Headers feature a pair of high flow catalytic converters and venturi style merge spikes to optimize exhaust flow as well as improve exhaust scavenging. As a result, these Long Tube Headers will dramatically increase the rear wheel horsepower and torque of your Pony throughout the entire RPM range. Stainless Power's Long Tube Catted Headers are perfect for those GT owners who are on a quest for more power and better performance, without the need of breaking their piggy banks.

      High Flow Catalytic Converters. Stainless Power's high flowing catalytic converters are engineered to outperform the restrictive stock cats. The included high flow catalytic converters provide a significant increase in exhaust flow for a measured improvement in horsepower and torque at the rear wheels.

      Superior Construction. Stainless Power Headers are manufactured to Stainless Works exact design specifications. Stainless Power Headers are CNC mandrel bent from 1-7/8" diameter, 304 stainless steel tubing for excellent exhaust flow and long lasting corrosion resistance. These Long Tube Headers feature TIG welded construction, as well as laser cut 3/8" header flanges for additional strength and leak-free performance.

      24-Month Guarantee. Stainless Power is Stainless Works value-line brand of exhaust products designed for the cost conscious consumer that wants a high-quality product at a reasonable price. Stainless Power is so confident in the quality of their Long Tube Headers that they are backed by a 24-Month guarantee on material and workmanship.

      Required Upgrade. To realize the full power potential that these Long Tube Catted Headers have to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

      Application. These Stainless Power Long Tube Catted Headers are specifically designed to fit the 2015 to 2023 GT Mustang equipped with the Coyote 5.0L DOHC V8 engine. These headers and connector pipes are a direct bolt on to the stock 2.5" exhaust system.

      Technical Note. Not legal for use on pollution controlled motor vehicles; intended for off road use only. These Headers are intended for left hand drive applications only.
