Review & Install Video

Improves Horsepower and Torque. Make everybody eat your dust by installing a set of Pypes Long Tube Headers on your Coyote powered GT Mustang. Engineered to improve the exhaust flow of your 5.0L Mustang, these Pypes Off-Road Headers will increase rear wheel horsepower and torque. Increases of 27 RWHP have been seen without a tune and well over 50 RWHP with a custom tune. Pypes 1-7/8" Long Tube Off-Road Headers are ideal for use on naturally aspirated 5.0L Mustangs, but really come to life when you decide to step up to a bigger cam or supercharger.

Quality Construction. Pypes 304 stainless steel Long Tube Exhaust Headers are manufactured using step tube technology. These Long Tube Headers are constructed from free flowing CNC mandrel-bent 1-3/4" primary tubes that step up to 1-7/8" and then merge at a 3" collector. The collector features a power spike design for excellent exhaust flow. Pypes Long Tube Headers are then completed in a bright polished finish for impressive good looks.

Required Upgrade. To realize the full power potential that these Long Tube Off-Road 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 Pypes Long Tube Off-Road Headers are specifically designed to fit the 2015 to 2017 GT Mustangs equipped with the DOHC Coyote 5.0L V8 engine. These Headers with connection pipes are intended to be installed with an aftermarket 3" catback exhaust system.

Please Note. Oxygen Sensor Extensions are required for installation. Sold Separately.

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.

2017 long tube headers

The headers are high quality. With that said. The bolts they send in the kit absolutely DO NOT FIT. USELESS. Big improvement in power with a tune.

Currently running flowmaster outlaw catback exhaust system.. will these fit ? Do I need to buy anything extra or will I be able to weld them on ?

Jm433d

  • The Pypes Long Tube Off-Road Headers are compatible with the Flowmaster Outlaw Cat-Back Exhaust and should have no fitment issues. A tune and O2 sensor extensions would be required. We recommend using clamps to install instead of welding, to ease service of parts such as the trans and the clutch.

Will these work with an AWE track catback exhaust system?

MikeP

  • These Headers with connection pipes are intended to be installed with an aftermarket 3" cat-back exhaust system. The AWE cat-back will step up to a 3" exhaust but will 2.5" where it connects to the headers.

Would these headers fit with the Ford performance x pipe without any issues?

Taylor

  • The Ford Performance Cut and Clamp Resonator Delete X-Pipe is cut and clamp so it will work inline with these. If you have any other questions about your exhaust setup please feel free to call or chat in.

Can you please tell me if headers for $994.00 as a kit, if they are in stock? Thanks for your time.

StevenE

  • It is currently 899.99 as a kit of 2 headers and the connection pipes for an aftermarket 3" catback exhaust. Currently, the item is out of stock and we do not have a projected time for when they will be back in stock.

I have a 2015 mustang gt with Corsa cat back extreme. Will these headers connect without issue? I have 3in midpipes and my helix xpipe is 3in also.

  • The Pypes Long Tube Off-Road Headers will connect to the Corsa Xtreme Cat-Back Exhaust without any issues.

I have a Ford performance x pipe and roush axle backs on my mustang. Will these fit?

Austaust

  • The piping size of your x pipe is 2.75 inches. The connecting piping of this Pypes system is 3 inches. So minor modification may indeed be needed to get these two pipes to connect.
