    Increases Power and Performance. Replace the restrictive factory Mid-Pipe Resonator on your Coyote Powered Mustang with the Roush Resonator Delete-H Pipe to reduce back pressure and increase exhaust flow. After installation, you will experience an increase in horsepower, torque and overall engine performance.

    Muscle Car Rumble. Roush's free flowing H-Pipe for the 2015-2019 GT Mustang not only eliminates the factory resonator to help increase power, but it also adds a deep muscle car rumble to the sound of your exhaust with its classic "H" crossover pipe design.

    Reuses Stock Cats. This Roush Performance H-Pipe requires cutting and removal of the factory mid-pipe resonator. Then your Roush replacement simply clamps in place reusing the stock clamps. Best of all, it reuses your original factory catalytic converters, saving you money and keeping you smog legal at the same time.

    Lightweight. The Roush Performance Cut and Clamp H-Pipe is 12 lbs. lighter than the factory mid-pipe resonator. It's perfect for street, track and drag racers who are looking to shed unwanted weight in the pursuit of quicker times.

    Stainless Steel Construction. Manufactured from 2.5-inch diameter free-flowing mandrel bent stainless steel tubing for its durability and corrosion resistance, this Roush Performance H-Pipe will improve exhaust flow and last a lifetime.

    Warranty. Roush Performance is so confident in the quality and workmanship of their Cut and Clamp Resonator Delete that they back it with a 3-Year Limited Warranty. Some exclusions may apply, please see manufacturer's warranty for complete details.

    Application. The Roush Performance Cut and Clamp Resonator Delete H-Pipe is specifically designed for use on the 2015-2019 GT Mustangs equipped with the coyote 5.0L DOHC V8 engine, including Fastback and Convertible models.

        Anyone know the length dimensions? Passenger and driver side? I'm trying to replace the X Pipe I currently have.

        Can I install this with the Flowmaster Outlaw axle back exhaust with perfect fitment? Or would this require some welding and cutting?

        • Yes, this h-pipe will work with the Flowmaster outlaw exhaust without having to do any modifications.

            2018 Resonator delete

            Had a Roush "cut and clamp H pipes" resonator delete recently installed on my 2018 Mustang GT 5.0L. I had it done at the dealer; which I recommend; as opposed to a muffler shop. I like to keep goodwill with my dealer. They can be a great resource. Great fit and finish on the product. Cold start up is definitely louder. Active Exhaust Management still functions properly. Exhaust overall is a bit louder. Doesn't "drone" at cruising speed. Nice low throaty rumble. KandN cold air kit is next.

            Love the sound with the quad tips. nice deep tones, even at Idle. Those cold starts are super! Had the Ford dealer install the H pipe. $50. Cut, slip and clamp 30 min max.

            good quality, haven't decided if its too loud

            Have a 2018 GT pp2 with active exhaust, and wanted to get just a bit more volume out of it, but really like the stock exhaust note. After having it installed, the old exhaust note is still there, but a teeny bit of rasp. Its definitely a fair bit louder, but still seems like something you could drive quiet if you want to. Quiet mode doesnt sound HUGELY different than with the stock midpipe. I have only driven like 10mi with the exhaust on it as its been raining etc... but it doesn't SEEM like it'd drone, especially with the ability to just put it in quiet or normal mode and quiet it down, but I do worry about cold starts when its not started in quiet times. Fit and finish is good, and parts and instruction manual (which i had to print out from roush's site) was very clear. Stainless steel was ideal because aluminized steel seems to corrode or rust decently quick. I'll update my review after I get some more miles on her, but so far I think it's good.
