XForce 1-7/8 x 3-Inch Varex Long Tube Catted Headers with Cat-Back Exhaust System (15-17 GT)

More Horsepower and Torque. Improve the power and performance of your 2015-2017 GT Mustang by installing an XForce Varex Full 3" Exhaust System. This XForce Varex Exhaust features a pair of 1-7/8" Long Tube Headers and High Flow Metallic Catalytic Converters that will greatly improve the exhaust flow of your coyote powered GT, when compared to the factory setup. This System not only improves the power of your Mustang, but also improves its sound with a pair of adjustable Varex Mufflers.

Adjustable Sound. By installing a XForce Varex Full Exhaust System, you can dramatically change the sound of your S550 Mustang's exhaust from a mellow street sound to a rich, throaty race car growl or anywhere between with just a push of a button. This XForce Varex Exhaust features a pair of electronically adjustable Varex performance mufflers. Close them when driving through a residential area to stay low key. Then open them up to let your coyote howl while speeding down the highway.

How It Works. XForce Varex performance mufflers utilize a sophisticated internal electronic butterfly valve mechanism to direct the exhaust flow within the muffler. In the open position, the valve "uncorks" the exhaust flow allowing it to take the path of least resistance. The muffler now acts more like a straight-through muffler for a rich throaty race style exhaust note. In the closed position, the valve blocks the exhaust flow, forcing it through the chambered paths to produce a classic, mellow street friendly sound. This unique design is perfect for personalizing the power and sound levels of your Mustang to suit your own specific needs.

Full Exhaust Kit. The XForce Varex Full Exhaust Kit is a complete 3" system from headers to tips. This kit includes a pair of 1-7/8" Long Tube Headers, a pair of High-Flow Metallic Catalytic Converters, a Mid-pipe Resonator, a Cat-Back Exhaust with Varex Performance Mufflers and a set of 4" Slant Cut Tips.

Stainless Steel Construction. This XForce Varex Exhaust System is manufactured from high quality stainless steel tubing for superior durability and corrosion resistance. The Long Tube Headers are constructed from 1-7/8" diameter piping that merges into 3" collectors for superior exhaust flow. The rest of the System features smooth mandrel-bent 3" diameter tubing to eliminate any power robbing kinks.

Direct Bolt-On Installation. Engineered to be a direct upgrade replacement, this XForce Varex Exhaust System will easily bolt on without any modifications required for a straight forward installation. The control module that powers the muffler butterfly valves can be plugged into your Mustang's 12v accessory outlet for easy plug and play operation or permanently connected to a 12v source - the choice is yours.

Required Upgrade. To realize the maximum power potential that this XForce Varex Full Exhaust System has to offer, AmericanMuscle highly recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. This XForce Varex Full 3" Exhaust System is designed as a direct fit bolt-on upgrade for all 2015 to 2017 GT Mustangs equipped with the DOHC coyote 5.0L V8 engine. These Headers are intended for left hand drive applications only.
