    Review & Installation Video

    Review & Install Video

    Hey, guys. I'm Justin with AmericanMuscle.com, here with my detailed overview of the Pypes Catted Long Tube Headers with 1 and 7/8 inch primaries fitting your 2015 and up Mustang GT. All right, guys, this overview is gonna cover the basic construction of the Pypes Catted Long Tube Headers, what you can expect as far as performance and benefits, and then finally we'll do a quick little walkthrough on the install. And speaking of the install, this one's gonna get a full three out of three wrenches on my difficulty scale. Long tube headers are always a chore on the Coyote-powered Mustangs and these are no different, and we'll have a little bit more detail on that later on. The Pypes Catted Long Tube should appeal to anyone with a newer S-550 GT out there who is looking to step into one of the more serious bolt-ons and doesn't want to totally destroy their budget or wallet in the process.

    Improves Horsepower and Torque. Give the guy in the opposing lane a run for his money by installing a pair of Pypes Long Tube Headers under the hood of your GT. Pypes Headers are engineered to increase the exhaust flow of your Coyote powered Mustang for an improvement in rear wheel horsepower and torque. Increases of 27 RWHP have been seen without a tune and over 50 RWHP with a custom tune. Pypes 1-7/8" Long Tube Headers are great for use on naturally aspirated 5.0L Mustangs, but really come into their own when you decide to step up to a bigger cam or supercharger.

    Make Some Extra Noise. Pypes Long Tube Headers not only improve the performance of your 5.0L V8 powered Mustang, but they will also improve its sound. With its high-flow design, these Long Tube Headers are less restrictive than stock allowing you to pick up a few decibels in your exhaust note for a more aggressive sound.

    High Flow Cats. Pypes high flowing catalytic converters are designed to outperform the restrictive factory cats. The included high flow catalytic converters provide a significant improvement in exhaust flow for a measured increase in rear wheel horsepower and torque.

    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.

    Calibration Required. Installation of this Pypes Long Tube Catted 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.

    No CARB Certification. These Headers are not CARB certified, therefore they are not legal for use in California or any other state adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    Application. These Pypes Long Tube Catted Headers are specifically designed to fit the 2015 to 2017 GT Mustangs equipped with the DOHC Coyote 5.0L V8 engine. These headers and connector pipes are a direct bolt on to the stock 2.5" exhaust system. These Headers are intended for left hand drive applications only.

    Came undamaged and well packaged. Dropped off at a performance shop and had the car back the same day. Loaded Bama's Ghost Cam tune with it. Sounds incredible. Only complaint is the passenger side headers ...

    The figment on the headers was perfect. The mid pipe almost perfect. I can really feel the power gains especially after the tune. The car is much louder now. I would reccomend these to anyone.

    Will these connect to a cat-back like the AWE that have a 2.5 inch connection point?

    EricE

    • Hey Eric, There is a stepdown pipe that would allow this system to connect to a 2.5" pipe

    Does this fit with the factory resonator? Basically, trying to keep my car to pass inspection still. Living in Texas. But wanna boost power, louder and get that deep, throaty sound. Thank you!

    AntonioF

    • Your car should pass a TX state inspection without the stock resonator. Since it is not the primary muffler replacing it with an H or X pipe is the perfect solution. Plus, that stock resonator is going to hamper any gains you are looking for with installing the full length headers.

    Pypes 1-7/8 in. Long Tube Catted Headers (15-17 GT) It is with tube cats right? Will i Need O2 Ext. ? Will it fit to Eu model 2016 GT 5.0? Drive side is on the left.

    FothD

    Would these bolt up to the MBRP 3" street cat-back?

    Nedim

    • Hello! The connection pipe on the Pypes Long Tube Catted Headers steps down to 2.5 inche to mount to the factory exhaust. It may require some modification to mount to the MBRP cat back.

    Will these pass inspection?

    CobraCommander

    • These will pass inspection in states that have not adopted the California CARB regulations. Use of these headers however will require a new tune on your vehicle as the flow rate will change from the stock shorty headers.

    Will this work with the x pipe with the exhaust on the sides like the one from a boss 302

    Strahtoz

    • The Pypes Long Tube Catted Headers - 1-7/8 in (15-17 GT) will work with the Ford Performance Boss Style X-Pipe and Side Exhaust - Fastback (15-17 GT) item #384704 (www.americanmuscle.com/boss-quad-exhaust-2015gt.html). The video that is posted on the Boss Style X-Pipe page will show you that the X-Pipe can be used with long tube headers.

      Great sound and power

      I used a lift when I did my install. Talk me 8 hours from start to finish running into no issues, and didn't take any breaks. Install went well, it's just hard due to working in a tight space. The rear o2 extension pig tails did not line up/work with my oem harness, but the front 2 o2 extensions worked fine. Overall good product. Only bad thing is that the o2 extensions did not work! Well worth all the work!

      Came undamaged and well packaged. Dropped off at a performance shop and had the car back the same day. Loaded Bama's Ghost Cam tune with it. Sounds incredible. Only complaint is the passenger side headers rattle against the motor mount stud. Currently trying to solve that small issue. Definitely feel the power!

      Very loud

      These long tube headers are what you really want. They are aggressive and demanding you to step on the gas. Absolutely love them.
