Description
More Horsepower And Torque. See a significant increase in the power and performance of your 5.0L coyote S550 Mustang with an American Racing Headers Catted 1-7/8″ Long Tube Header and X-Pipe Long System. These American Racing Headers and X-Pipe will greatly improve your GT Mustangs exhaust flow, over the restrictive stock manifolds and resonator Mid Pipe, for a considerable increase in rear wheel horsepower and torque.
Race Car Growl. The included X-Pipe not only eliminates the factory resonator to help increase power, but it also adds a loud raspy, race car growl to the sound of your exhaust with its modern “X” crossover pipe design.
Quality Construction. American Racing Headers are manufactured in the USA from mandrel-bent 1-7/8″ diameter 304 stainless steel tubing that merges into 3″ collectors with scavenger spikes for superior exhaust flow. These long tube headers feature a one piece 3/8″ header flange for additional strength, leak-free performance and an OEM style fit.
Required Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle highly recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.
Cut & Clamp Installation. American Racing Headers designed their 3″ Long Systems to “step down” at the rear axle, which allows you to reuse your stock mufflers or the 2-1/4″ aftermarket axle-back of your choice. Installation will require cutting and reusing the stock muffler assemblies and clamping them in place. Clamps and detailed instructions are provided.
Application. This American Racing Headers 1-7/8 x 3 in. Catted Long Tube Header with X-Pipe Long System is designed to fit both Fastback and Convertible 2015-2017 GT Mustangs equipped with the coyote 5.0L DOHC V8 engine. Requires the use of the factory or a 2-1/4″ aftermarket axle-back exhaust for proper installation.
Technical Note. Long tube headers are not legal for use on pollution controlled motor vehicles; they are intended for off road use only.
Please Note.These Headers are intended for left hand drive applications only.
