Boost Your Mustang's Performance. Are you looking to further boost the power and performance of your 2011-2014 GT500? If so, consider installing a pair of MBRP Long Tube Headers under the hood of your mighty serpent. MBRP Headers are engineered to improve the exhaust flow of your supercharged Shelby for a dramatic increase in rear wheel horsepower and torque. When installed with a MBRP Off Road H-Pipe and a Race Series Cat-Back Exhaust you can expect to see gains of 44 horsepower and 28 ft/lbs of torque over the original factory exhaust system. 1-7/8" Long Tube Headers are a great choice for use on a stock Shelby GT500 Mustangs, but really come into their own when you decide to do a pulley swap or step up to a bigger cam.

High Quality Construction. MBRP's Long Tube Exhaust Headers are fabricated from high quality 304 stainless steel for superior strength and enduring corrosion resistance. These Long Tube Headers feature free flowing CNC mandrel-bent 1-7/8" primary tubes that merge into 3" collectors. Each collector features a merge style spike design for excellent exhaust flow. These Headers also employee heavy duty, laser cut 3/8" header flanges for additional strength, leak-free performance and an OEM style fit.

Calibration Required. Installation of these MBRP Long Tube Headers will require the use of a Handheld Tuner to reprogram the vehicles computer (ECU) for operation. By reprogramming your Mustangs ECU you will be able to realize the full power potential that these headers have to offer.

Application. These MBRP 1-7/8" x 3" Long Tube Headers are specifically designed to fit all 2011-2014 Shelby GT500 Mustangs equipped with the Supercharged DOHC V8 engine. MBRP Long Tube Headers will require the use of a MBRP 3" mid-pipe and cat-back for proper installation.
