ACCELATEC Resonator Delete H-Pipe Aluminized Steel GT 2015-2019 is rated 4.8 out of 5 by 62.
Rated 5 out of 5 by from Excellent value! This H pipe is great. I have a new 2015 GT, and stock is too quiet. Figured to cut off resonater and do and X or H. Chose the latter as I wanted something more muscle car and less European. WITH installation this cost me $145 and the car sounds awesome. The H pipe fit right on, no welding. Weighs less than the resonater so added bonus. If I add Flomasters or catback I'll have saved money. This pipe is a great start. Highly recommended.

Rated 5 out of 5 by from Perfect for making the GT sound like a GT! Bought the H pipe because I wanted a deeper tone over an X pipe. I did install this with a Flowmaster Outlaw axle back (whicked loud btw), but it was super easy to instal. The factory exhaust comes off very easy. The videos CJ does are helpful if you're not sure. Took me about two hours to install everything by myself with basic handtools (although I use an angle grinder with a cutting wheel instead of a Sawzall in) my driveway. And it's noticable lighter than the stock setup as well. Well worth the price.

Rated 5 out of 5 by from Looking for that muscle car growl? Here it is. I combined this H-PIPE with a Roush axle back exahust and it roars. Cold start is great and when hitting the gas it really gets loud. No drone at cruising speeds. Install time was 4 hours. I did the work with a jack and jack stands. It does take two people to do the install, I wouldn't recommend doing it alone. Check out the video for a taste of the finished product. Again, this is the H-PIPE combined with the Roush axle back. Enjoy

Rated 4 out of 5 by from Great bang for the buck! I bought it on sell from CJ Pony Parts for less than $84 and with free fast delivery!!. I did the installed myself and it was easier than expected thanks for their step-by-step video. The hardest part was the cutting of the resonator after I removed the system. (But definitely make sure to measure twice and cut once.) It sounds a bit deeper at idle than the stock resonator running with stock axle backs which is what I was going for. I'm super happy with my purchase and by the speedy order processing, shipping, and delivery of CJ Pony Parts; they definitely will continue to get my repeat business. One side note- which is not a deal breaker for me- but it is stamped /engraved with "Made In Canada" in more than one spot so I'm not completely sure why the product "Features and Benefits" says " Made In The USA".

Rated 5 out of 5 by from Love This Product I bought the Aluminized Steel H-pipe as it was cheaper, I live in Arizona so I am not worried too much about the wet weather causing damage to it too soon. I installed this about 3 months ago and so far I am very happy with my purchase and the sound. I installed this along with 2 flowmasters super 40s and left the stock tips. delivery was very fast. I installed the H-pipe by my self and it was not that difficult aporximately 2 hours of work. I cut to the exact measurements as the video suggests but it seems as thought the cut should be less because the pipes to me seem to not completely sit all the way in. it is on there nice and secured but like another person said you are definetly going to have some exhaust leakage.

Rated 5 out of 5 by from Super sound improvement! I bought the aluminized H-pipe because the stock exhaust on my 2015 Mustang GT was too quiet. Had a muffler shop install it because I don't have access to a lift or ramps so I could work under the car. Shop had it installed in less than an hour. Now my GT sounds like it should have from the factory. It's noticeably louder at startup but idles very quietly thereafter...just slightly louder than factory. But now it sounds like a muscle car should with a deep, throbbing sound and with no drone while cruising. Makes me smile every time I drive it.

Rated 5 out of 5 by from Turned out much better than expected !! I got my aluminized steel H pipe installed today. First off, it's a well made piece with a very nice weld job. It took less than an hour to complete the job and the mechanic I helped with it also mentioned how smoothly the install went. The best surprise came when I started it up. It is about as quiet at idle as it was with the factory resonator, but when you romp on it, the exhaust note is a deep rumbling snarl. On the highway, there is no drone whatsoever, and at 70 mph I think it is quieter than stock until you step on it and then it just sounds fantastic,- slightly louder than stock, but not obnoxious. The car also seems to rev more freely and have a slight power boost as well. Absolutely a win -win situation. An excellent modification.

Rated 5 out of 5 by from Great first mod for a 2015/16 Mustang GT Great price, easy to install and great sound! I am using it with my stock mufflers and sounds great!

I currently have the Ford Performance resonator delete X pipe (2016 GT), but want to move to an H pipe for that deeper muscle car sound. Will it still fit?

Asked by: mustangmike31
We have not went from one of those pipes to the other. You should be okay but you may have to either trim a small amount off of your factory exhaust or add some to it depending on how this lines up once installation is attempted.

Asked by: Whitepony5
There would not be any difference.

ACCELATEC Resonator Delete H-Pipe Aluminized Steel GT 2015-2019 Video Transcript
By Bill Tumas: For years an H-pipe has been a popular upgrade for Mustang enthusiasts and 2015 is no different. It's just a little different on how it actually works. In previous models an H-pipe was usually used to get rid of the catalytic converters to increase flow to the exhaust and increase sound. The 2015, instead of deleting the cats, your H-pipe is going to delete the heavy factor resonator. Getting rid of the resonator is going to increase flow to your exhaust systems, save weight and give you a much better exhaust tone. Today we're going to show you how to install a resonator delete H-pipe on a 2015 Mustang GT.

The H-pipe is made of aluminized steel. It's going to be a direct replacement for the resonator, but will require cutting for installation. It's going to save weight and increase flow and is pretty easy to install.

For this installation you need a lift or jack and jack stands, 3/8 ratchet, 13 millimeter socket, 15 millimeter socket, tape measure, marker, sawzall and safety glasses.

A resonator delete is going to go right here. Replace the factor resonator. What we've got to do is unbolt the exhaust in the front, take the whole system off. We can cut it back here. You don't want to cut it on the car. The main reason why we cut here, it's going to provide sparks. This plastic cover here is your fuel tank. Not a good place to cut the car. The exhaust is easy to get off. So we're going to pull off our cat-back and then start the cutting.

We have a stock system or an aftermarket axle back. The removal is the same process. Remove these two bolts here, get rid of the hangers, then remove the four 15 inch bolts up front.

I'm going to line up our H-pipe to figure out exactly where to cut. We know it's about four inches off here. We'll just line it up in the front and measure off four inches. That'll put us right there in the meet, which is where we want to be. Make our mark and cut.

There we have a cut and we can install our resonator delete H-pipe. Line it up with the factory clamps, push it in place and then you'll want to snug these down. So, tighten that clamp and repeat that process on the other side.

Now we can put our tail pipe assembly up into place. You'll want to tighten the bolts for the rear brackets and tighten your front bolts. You installation is finished.

Now let's fire her up with a resonator delete H-pipe. Removing the resonator, especially with this style muffler, it is loud.

Okay. As we kind of expected, we've done this before with the Roush mufflers with the H-pipe with the resonator delete, It's loud. I mean there's no way around it. The quad tip I think is actually even louder than the standard single tip version is going to be. It's that aggressive Roush tone that we've been used to for years on their mufflers now. They've always had a nice sound. This is just a, like I said it's a louder version of it with the H-pipe installed. It's a little deeper sounding at lower volumes. I know a lot of people are going to ask how does it compare to an X-pipe. The H I would say is a little bit deeper at a cruising rpm, like a 1000 to 2500. Somewhere in that ballpark.

Wide open throttle, it's just as loud. It's just as raspy. The pitch is probably a little lower with he H-pipe, but wide open it's a pretty similar sound. I would say the biggest noticeable difference is going to be like a cruising rpm, like I said it's a little bit of a deeper tone.

Here we are, sixth gear. Highway speeds. Again, the dreaded 2000 rpm drone zone. It's not droning. You can hear it. It's back there. Definitely is in stock. You're not going to fool anybody about that, but it doesn't have a sound you couldn't live with on the highway. It's not going to kill your eardrums. It doesn't have that kind of monotonous sound that would get on your nerves after a while.

Yeah, you downshift, it gets loud in a hurry. We get back to the highway speeds, very livable for the highway driving.

Getting rid of the factory heavy resonator, putting in the resonator delete H-pipe totally changed the attitude of our 2015 Mustang GT. The exhaust on it now, the additional flow, the sound got much louder and much more aggressive. So now the other benefit, we saved almost ten pounds over the factory resonator. Installation is pretty straightforward. It will take you about an hour. You should be back on the road in no time.
