        Currently have the Roush X Pipe with Roush Axlebacks, I want to try the H Pipe. I’ve heard it gives a much deeper tone, will the fit with the cuts I’ve already made to fit the X pipe?

        My Mustang currently has a BAMA tune specific to the modifications already installed. Will I need a new calibration after this h-pipe is installed?

        • No you will not need a new tune.

            Now my neighbors really hate me!

            Love the sound of the H pipe over the X pipe. More of a deep rumble. Definitely paid more for the Roush pipe then other brands, but it went on a Roush, so it was the obvious choice for me. Install was a lot of work for 1 person, on the floor, with the car on jack stands. AND FYI: if you look at the rear pipe opening’s, you will notice that one of them is curved slightly outward, this should be on the passenger side when installed, trust me it makes a difference. Well worth the work and effort. Install was about 2 hours working solo.

            Exhaust Upgrade

            Already had the Roush Axle back exhaust and deleted the resonator for the H-Pipe. Reduced weight of the car and added a little more torque. Great Mod!! The car sounds very aggressive but keep in mind that you will wake up the neighbors early in the morning!! Overall, very happy with it.

            H-Pipe for the perfect muscle car sound

            I have a 2017 GT convertible with the stock mufflers. I added the H-pipe due to desire for a louder exhaust coupled with the trepidation that by changing anything on the exhaust would make for a "droney" top-down nightmare. Well I cannot tell you how relieved I was that I got an increase in volume, but with a good deep rumble that makes it sound like a tough car that an adult on good speaking terms with neighbors owns. There is no drone and the exhaust sounds very similar if not the same on the interstate with the top up and the cruise set at 75. Following the directions on the Roush website, I still thought the install was difficult due to inexperience with exhaust work and angling a large Sawzall under the car without damaging any heat wrap or my vital facial areas. Wear goggles, gloves, and a hat--metal dust goes everywhere. I had to loosen the hangers over the rear axle and a joint on the left header that wasn't mentioned in the instructions. It was a tight squeeze but I got it attached. The instructions call for torque specs of around 35 ft. lbs, I believe. That wasn't enough, and I had some rattles. After I tightened it a little more, no rattles since (approx. 100mi). Overall I am very pleased with the part.

            Best H pipe out there

            I swapped out my SR performance X pipe to a Roush H pipe and is sounds so much better and gives me that deep tone that I’m looking for.

            Race car deep sound truly the best product

            I think it’s the Top-of-the-line product! (especially going on a Roush mustang S2) This sounds like a race car now! I watched all the videos online. I tried to gather all the information I could. I watched installation versions from different people. Compared products. I made notes. I decided what I wanted to do and what plan of attack I knew that I wanted stainless steel and I knew that I wanted to get the top-of-the-line. so it was between the X pipe and the H Pipe. I knew that I wanted it to last. Wanted deep tones and aggressive sounds. So stainless steel... so I knew that I wanted to get the H pipe.. The H pipe is more of a muscle car deep tone sound. the X pipe is more raspy like a Japanese sound. Think of your neighbors (with the high shrill raspy noise at high rpm) type of sound. it’s more irritating in my opinion. I followed all the Roush instructions, I used all the materials that Roush instructions called out for. I had it removed and ready when the part arrived it. I bolted it right into place with no problems. Supported the aft exhaust system with a jack, measured back 5.5 inches after the resonator. Easy on car installation. The best choice.

            Went from a pur to a ROAR!

            This was the exact piece I needed to finish my ROUSH exhaust system since I bought the axle back exhaust instead of the cat-backs.

            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.

            Great Sound

            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.
