Product Description

MRT Stainless Steel Resonator Delete H-Pipe for all 2015, 2016 and 2017 GT Mustangs.

With the introduction of a fully redesigned chassis came a totally rerouted exhaust path with features that were not present on the previous generation. Ford did away with the factory h-pipe and replaced it with a fully welded up resonator box that crosses the exhaust pulses. Not only is this extremely restrictive, but it’s also obnoxiously heavy. MRT has listened to the community and introduces their solution to this problem!

Available only at CJ Pony Parts, Mustang Racing Technologies, aka MRT, has engineered this Resonator Delete H-Pipe that easily replaces that bulky and restrictive OE Resonator. Manufactured completely out of CNC mandrel bent 304 Stainless Steel tubing, this H-Pipe will bolt-in place once two simple cuts have been made and the OEM segment is then unbolted and removed. The new H-Pipe will reuse the two factory clamps found on front and MRT will supply two new clamps to use on the rear section after the applicable cuts have been made.

Features and Benefits:
- Replaces Factory Resonator with a More Efficient H-Pipe
- Significant Weight Savings Over the OEM Resonator
- Aggressive Exhaust Note Even With OE Mufflers
- Simple Cut-And-Clamp Bolt-In Installation
- Full 304 Stainless Steel Construction with Precision Welds
- CNC Mandrel Bent Tubing Ensures a Smooth Exhaust Path and Precise Fit
- Hand Built in the USA at MRT Headquarters
- Includes All Necessary Hardware and Clamps

*This Resonator Delete H-Pipe does NOT require any welding.
*Tuning changes are NOT required for a proper installation.

So what advantages does an H-Pipe have over an X-Pipe? The most noticeable advantage is sound. X-Pipes tend to provide more of a raspy exhaust note and overall just be a bit louder. If you plan on doing other modifications to your exhaust, going the X-Pipe route may not be the right answer for you. Whereas an H-Pipe typically provides that deep muscle car sound that everyone seems to look for in there Mustang, providing more room to grow for future modifications to your exhaust system. Not only can you achieve the perfect exhaust note, but H-Pipes have proven power benefits right where you want them. Providing a decent boost in low-end torque. While most X-Pipes usually will only show an increase in power higher up in the rpm range. MRT has always recognized the advantages of the H-Pipe versus the X-Pipe and continues down that proven path with this beautifully engineered piece.

MRT Resonator Delete H-Pipe Stainless Steel GT 2015-2017 is rated 4.8 out of 5 by 48.
Rated 5 out of 5 by from Amazing item Installed the h pipe over the weekend on my roush stage 2 with quad tips. I have to say it was a bit trickier as roush had already cut the pipes when they installed their system. Needless to say I had to cut the resonator and clamp it one more time, followed the guidelines from Bills video and it worked like a charm. Mit was harder because the quad tip mufflers have a second set of hangers but after a little patience it was good to go. The result is amazing , and sounds awesome. I can feel the difference especially at take off. Can't wait to add the roush CAI when they make it available. Anyone with a 15 mustang should add this.

Rated 5 out of 5 by from How the stock mustang should have sounded This is an excellent, essential & inexpensive upgrade. Get rid of the stock resninator and you'll wonder why on earth did Ford fit it in the first place. The sound is perfect for those wanting a slightly louder more sophisticated sound without being intrusive. Most noticeable on cold startup & moderate to hard aacceleration it just sounds great with no raspiness and the H -Pipe design gives it a discrete muscle car burble. Pair with the JLT Cold Air system and you have the perfect induction & exhaust system and on top of that m getting 25mmiles per gallon (UK) average since leaving the showroom an increase of 25% over official figures

Rated 4 out of 5 by from Bad build quality but overall nice choice! *VIDEO* Soundcheck video: I did a recording with a nice handy recorder in my underground parking and measured some db(a) values. Check out the attached video! :) Got it installed on my 16GT. Build quality is not that good. The ends of both pipes (directing to the rear) were not round! With pipes I expect good weldings and no deformations. The shopy guys had to hammer it about 10 mins to make it fit. So the installation time was nearly 1 hour instead of 45 mins. As other buyers reported the same MRT should improve - can't be too difficult. Overall I am satisfied. No leaks, very nice deep tone, slightly louder, more aggressive on higher rpms. Don't expect any noticeable performance gains from it.

Rated 5 out of 5 by from Like a proper American V8 should sound... The factory GT exhaust has a nice tone but it's a little too quiet for me. This h-pipe gave me a slightly louder and deeper sound at idle and definitely more rumble on acceleration. A little drone at low RPM's but sounds totally stock in normal cruising range. The h-pipe's flared ends are a tight fit to the factory pipes (as it should be), so I assembled everything on the ground and then hung the complete assembly. File a slight bevel on the cut ends, hit it with a little WD-40, then...with a little persuasion, it'll go right together.

Rated 4 out of 5 by from Loud! With roush axel back For the price i feel this is a great stainless option without going with a full system. It is super, push the clutch in and coast past a cop, loud with the roush axel backs but sounds amaizing. Old school muscel sound at idle and modern racecar at WOT. Sounds a little like an exhaust leak/open headers in the cab but perfect outside the car. Doesnt really drone at highway speeds and i havent had to turn up my radio volume to compensate, but you can absolutely hear it. MRT does need to get with their shop monkeys though, and turn down the chuck pressure on their mandrel as the pipe necks were a bit disformed and marred. Welds are ugly but solid too. Easy install, took about an hour because i was on the ground and couldnt find a file.

Rated 5 out of 5 by from Video is not accurate for a 2016 GT I bought this for my 2016 Mustang GT. You cannot take the tailpipes and mufflers down (after the cuts behind the resonator) by just unbolting the 2 hangars above the differential. There are 2 additional hangars near the exhaust tips. Also, while I did achieve "no leaks" with the clamps provided, I feel it is well worth having a muffler shop weld the tail pipes to H-pipe union. Cost $20 total. BTW--now the good part--the sound is perfect to me. It is louder, noticeably so, but not obnoxious. No drone. You notice it at idle and when you accelerate moderate to hard. It is just right, to my ears. The perfect modification to make the 5.0 sound like its muscle!!

Rated 5 out of 5 by from Sounds Great! Finally, got rid of the resonator for this H Pipe, picked the H Pipe for deeper muscle car sound. Even with stock mufflers, it sounds great with a deeper rumble. Definitely a best bang for buck mod. Next is a CAI to open up the intake to go with the opened up exhaust. Installed with the rear up on ramps. It was tight, but got it done all by myself using jack stands to support the mufflers and a few rolls of paper towels to support the h pipe up front during installation. Took longer than expected, so if you don't have a friend around and a lift, it will take a few hours to get it all lined up and clamped down. The exhaust tips are lined up and spaced perfectly too. Wear gloves.

Rated 1 out of 5 by from poor build quality Let me start by saying that I like CJ Pony Parts people I've dealt with but this review is strictly about my product. First, I could have had my local muffler shop make and install this out of non-stainless for about $150 bucks but wanted something I could do myself without extra tools and would likely have nicer welds. Unfortunately the welding was mediocre at best (especially inside the tube where they burned through). And worst was the back "stretched" ends were not round and but stretched open enough. So if it went for the fact that I did this job at my buddies shop and he happened to have a lathe so we could turn down a large chunk of aluminum to hammer into the ends to open them up, I would have likely been sick without a car until I could get the part tto a muffler shop. BTW, all these extra steps took an extra two hours. I know one could say I just got a bad one, but for $239 I would expect they double check the clearances before shipping them. So it's installed now and I like the sound but i hope someone reads this from CJ and/or MRT to avoid this in the future. If I had to do it again is probably just take it to my muffler shop to make an h pipe. Im not mad, just disappointed.

Product Questions

Is the H-pipe resonator delete a 3 inch pipe or 2 1/2 inch?? I was thinking of matching it with the manga flow 3 inch competition Axle back, so in just want to make sure it work without cutting anything.

Asked by: Castig93
This pipe is the same size as the factory exhaust. You will still have to cut if you planned on pairing this up with the MagnaFlow competition Axle-Back and a small portion of your OE piping will be needed to connect the two.

Im looking to upgrade my factory 2016 GT exhaust and want to go with the Rouse Axel back. Is there any sound benefit by adding your H-pipe? If so would I save on instalation by doing both at the same time? Thanks, Brian

Asked by: BrianP
This will delete the factory resonator, when coupled with the Roush Axle-Backs the sound and performance will be much increased. You won't necessarily save on installation, but it will be easy to knock out both jobs while you are under the vehicle.

I have a 2015 Roush supercharged Mustang gt upgraded to phase 2 with the 80mm pulley... will this fit between with my kooks longtubes and the Borla ATAK catback? Atak comes with the x/pipe but much rather the h/pipe and worried about fitment.

Asked by: TIMLYLE143
No, it will not work without modification to your Borla Cat-Back. Where this would connect to your cat-back will be different diameter. You would have to purchase an adapter and a second set of clamps or have an exhaust shop weld the pipes for you.

I installed it and it sounds great, but is it supposed to leak a little by the clamps?

Asked by: widebodymustang
It is not supposed to leak, try tightening the clamps, and make sure the pipes are fully seated inside each other.

Will this product suit RHD Mustang (Australia)

Asked by: Ozistang
It should fit from what we have seen the cat back is all the same.

MRT Resonator Delete H-Pipe Stainless Steel GT 2015-2017 Video Transcript
By Bill Tumas: We have no doubt that the leading large factory resonator found in the 2015 Mustang is going to be a very popular modification among owners. The resonator is very heavy, and also very restrictive. Releasing it is going to save some weight on the car, give you more sound and more horsepower.

There's a lot of ways to lead it so far using an X-pipe, but we've been listening to our customers who have been asking for a way to do it with an H-pipe. We teamed up with MRT and offer this exclusive H-pipe resonator to lead.

We teamed up with MRT to offer this resonator lead H-pipe available exclusively here at CJ Pony Parts. It's a rack replacement for the factory resonator. You simply cut off the tailpipes, and use the factory clamps on the front. Now it's going to increase flow to your exhaust. Give you much better exhaust tones. It's going to save you 15 pounds over the factory resonator.

To start off, we're going to give you some stock sound clips.

For this installation lay a lift or a jack and jack stands, 3/8 ratchet, 13mm socket, 15mm socket, extension, flat blade screwdriver, measuring tape, marker, sawzall, file and safety glasses.

As we have shown you many of times in the past removal of the stock system is actually quite easy, but we do suggest a second set of hands to make it easier. The first thing you want to do, remove the two bolts for the two rear brackets. Don't worry about removing the brackets, there's actually a little hook so they're not going to fall off.

Now we'll move four to loosen the clamps to hold the resonator to the front pipes.

You may want to bend this tab up. There's a little stud that will stop it. You can slide the clamp down. Now you can pop these little hangers off here. Now the weights going to go forward, and you shimmy the system forward off the rear clamps.

Once you have the factory exhaust off you want to get it somewhere where you can cut it. What we're going to do is measure back six and a quarter from the center of the resonator. We're going to mark it, and then cut the pipes off.

You look at the H-pipe, you notice the one side has a slight curve to it. When put up into place the curve side is going to be on the passenger side.

Now we'll snug up these clamps and you're going to tighten them all the way down. We still may need to adjust them. We're just going to get them snug for now.

Before we install the stock tailpipe and muffler, you want to make sure you file this down. Get it as smooth as possible so it fits in the clamp.

Now we're ready to reinstall. We'll start by putting it back in the factory muffler clamp.

Slide the clamp into place, and tighten it down.

Now repeat the process on the driver's side.

Now let's hear how it sounds with the stock mufflers and our MRT CJ resonator lead.

She sounds pretty healthy even with the stock mufflers by getting rid of the resonator. It's a lot more exhaust volume, and it has a nice raspy tone to it as well without being too loud.

Driving the car and acceleration wise, it's only slightly louder than stock to be honest with you. You can really barely hear it. A little bit at the higher RPMs, then you can hear a little bit more of the aggressive tone of the muffler. Cruising wise, zero drone, zero noise at highway speeds.

It feels like a factory car until you down shift and get on it a little bit, then you can really hear the sound a little bit more.

This is the perfect choice if you're trying to keep the car subtle, want a little more sound but don't want to get into a full exhaust. Getting rid of the resonator. Like I said, you're going to save weight, it's going to increase the flow for sure and it gives you a nice sound without being overly loud.

In my opinion, had Ford not built the 2015 Mustang to be used in different markets across the world, this is probably how they would have made it sound. It's a very nice tone. It's actually very reminiscent of the stock systems found in the ‘11-‘14s.

The MRT resonator delete H-Pipe is going to get rid of your heavy restrictive factory resonator. It's definitely going to save some weight. It's going to free up some horsepower as well. It's going to work with either a stock or an aftermarket axle. Back to even that real muscle car sound. This part is available exclusively here at
