    Practical Power Boost. Get a practical power and torque boost for your Mustang GT with the Pypes 1-7/8-inch Long Tube Catted Headers. These long tube headers feature a “step” design wherein progressively larger piping is used at certain sections of the header, with the intention of allowing exhaust gases to leave your coyote engine faster, resulting in greatly diminished back-pressure and an increase in overall performance numbers. These headers benefit naturally aspirated engines, but can also be used with some of aftermarket engine mods.

    An Exhaust Note with Attitude. The Pypes 1-7/8-inch Long Tube Catted Headers doesn't just make your Mustang perform better, but sound better as well. This header system produces an attitude-filled exhaust note that starts at a low rumble during idling and builds up to a loud roar that’s on the deeper end of the sound spectrum. This exhaust note is sure to send shivers down the spines of the competition on track day.

    Performance Cats. The Pypes 1-7/8-inch Long Tube Headers include performance catalytic converters. These high-flowing cats will perform the job of a standard cat but in a less-restrictive manner. The high flow, less restriction provides your Mustang with the incredible performance boost.

    Heavy-Duty Build Quality. The Pypes 1-7/8-inch Long Tube Headers are crafted from heavy-duty stainless steel for strength and resistance to corrosion. The pipes are completely mandrel-bent for added rigidity less turbulence. The headers’ specialized “step” design starts out with a 1-3/4-inch diameter pipe, into a larger 1-7/8-inches, and finally ending with a 3-inch wide collector with all the joins being TIG-welded for strength.

    ECU Re-Tuning Recommended. While installing the Pypes 1-7/8-inch Long Tube Catted Headers will produce performance gains, it is recommended that an ECU re-tune be performed on your Mustang. This is to ensure that your engine and the new header system are truly in sync with the optimal performance gains.

    Not CARB Certified. The Pypes 1-7/8-inch Long Tube Catted Headers are not CARB-certified, making their use illegal in California or other states that have adopted CARB certification. Please check your local laws for permitted applications.

    Application. The Pypes 1-7/8-inch Long Tube Catted Headers fits all 2018-2019 Mustang GT models.

            Fit was perfect headers came with everything you need to install em the only thing I didn't like where the gaskets so I reused my factory metal ones now I did that because I only have 5k miles on the car and the factory gaskets are made better in my opinion the high flow cats work perfect as well I couldn't get my car retuned for 2 weeks because my tuner was booked out but 2 weeks of driving it with the e 85 tune i had on it never got a check engine light so that's a bonus car is definitely louder especially on a cold start you can feel the ground rumble but I have an H pipe and custom exhaust with flow master exhaust but it's quite enough on low rpms and aggressive enough on high rpms to make ppl move out your way either way great product epic sound very happy if I could I'd upload a video of my cold start
