Steeda's 304SS Resonator Delete X-Pipe for your 2018-2021 5.0L, Coyote powered S550 Ford Mustang GT is the best way to improve sound and increase performance at minimal cost, all while losing up to 7 pounds of weight. The X design, with its smooth transition, creates more scavenging effect than traditional H designs for increased power at high RPMs and a race inspired exhaust note. Unlike most 2015+ versions on the market, this 2018+ specific X-pipe allows you to retain the factory heat shield found on 2018 and newer GT models without cutting and expanding the X-pipe to retain the OE shields or chiseling off the OE shields. With mandrel bent 2.5"diameter tubing, the X-pipe easily installs between the factory catalytic converters and the factory mufflers. It is also compatible with virtually all aftermarket axle back exhaust kits. The T-304 stainless steel mandrel bent tubing will not develop surface rust typical with 409 stainless or rust completely through like aluminized mild steel. The flush fit exhaust clamps allow for shortening of the X-pipe if needed and prevent exhaust leaks common with expanded end kits.

NOTE : Cutting of the OE exhaust pipes is required for all resonator deletes on the market.

Product Benefits:
  • Up to +8 hp
  • Up to +9.5 lb/ft of torque
  • X-pipe design improves exhaust flow over factory resonator and H-pipe design up to 20%
  • 304SS will not rust like inferior 409SS or aluminized steel pipes
  • Aggressive race inspired exhaust tone
  • Sheds up to 7 lbs weight
  • Does not require tune
  • 32" overall length 
  • Band clamps allow cut to shorter length
  • Retains 2018+ factory exhaust heatshields
  • Band clamps allow for reinstall of factory resonator
  • Fits GT, Bullitt, and Mach 1 Mustangs

X-Pipe vs H-Pipe: Which Is For You?

2021 Mustang: Stock Exhaust vs. Steeda X-Pipe & H-Pipe on the Dyno!

CA Residents: Cancer and Reproductive Harm WARNING

Hi everybody Brian from here today to answer a very important question for you S550 owners to H-Pipe or to X-Pipe that is the question. Now we can understand the confusion because both of them look very similar to one another. They're both made of T 304 stainless steel. They both replace the OEM resonator both save a lot of weight off the middle of the car and both change the sound and add some performance to the car. So we're here to help answer and guide you toward which may be better suited for you. We'll start with the H pipe. The H Pipe will give you a little bit of a deeper sound. A little bit more of a muscle car sound. A little throatier, but not quite as a raspy up top. As we move on to the X Pipe that's we're gonna get your higher RPM raspiness and a real nasty growl as you get toward red line. As we referenced a moment ago, both of these are a replacement for the factory resonator. The tubing is the same size and we provide the clamps for a nice clean installation. Since these utilize the factory exhaust gives you your choice of any axle-back that you want so you can truly customize the sound of your S550. Now with regards to performance both of these are going to increase performance nearly equally the X Pipe will just slightly edged out the H Pipe in peak performance just by a little bit. So in all reality it comes down to the type of tone you're trying to get out of your exhaust and this brings us back to our original question. To H Pipe or to X Pipe. Which did you choose?

Quality X-Pipe
Quality x-pipe from Steeda! Sounds great with my active exhaust. I did end up having to bring the car to an exhaust shop and have them spot weld the supplied clamps in place. They kept loosening up after driving for a few days and would make the exhaust tips sag and move off center. There were also exhaust leaks when this would happen. The shop said this is a common problem. Other than that, I love it!

Bought this for my wife's 2022 GT/CS 6spd manual. It had 43 miles on it when I installed it. Directions and fit were perfect. Sounds awesome.

X Pipe in the garage
I installed this x-pipe in my garage on ramps and jack stands so not a lot of clearance. Was not too hard at all and took me about 2 hrs total. Looks excellent and sounds even better. If there was one thing I would improve is the bolt heads on the supplied clamps spin so you have to maneuver an open end wrench on top of the pipe to hold the bolt so you can tighten it. Some sort of fix for that issue would be much appreciated.

Happy Customer
Love it, with the active exhaust opened up it brings the sound track of my '19 Bullitt up to "wake the dead" as for the power gain, I can't say as the X pipe and the Tune went in at the same time so between the two there is a NOTICEABLE improvement in the way this pony kicks up it's heels from about 3500RPM and all the way to the top of the tach. As always, Steeda has delivered quality products at reasonable prices with prompt shipping.

Steeda X pipe
I purchased the Steeda 304 SS X-pipe while awaiting delivery of my 2021 GT PP to arrive. 10 days and 278 after it arrived I had it installed bye my local muffler shop. With Standard non-active exhaust it gave the car a nice exhaust note and eliminated the 'Drone' associated with the Factory resonator. I can drive 300-350 miles on a Saturday outing without a headache, I personally would recommend a resonator delete as 'the first modification' for the S550 mustang.

Great sound
I had a muffler shop install it. The sound is incredible. I'm also happy that for a lower price compared to Roush you get better raw materials. 304 stainless steel in the case of Steeda. Great mod for the money and woke up my stock 2020 GT with Active exhaust.

Steeda axle back muffler
Purchased Steeda axle back exhaust for my 2019 Mustang 5.0 GT, had Steeda do the installation and they gave me a great install price and I caught a sale on the axle backs. The axle backs coupled with a cold air system really allows the 5.0 to breathe, you will notice a significant awakening of the motor without any drone. I highly recommend and thus is my 4th GT.

2019 GT X-Piped
I installed the x pipe on my 2019 gt in less than an hour. Great buy, easy install with proper measurements for cutting factory resonator off and No Welding! Amazing sound with factory cat backs. Good job Steeda!

2020 Mustang GT
Installed this today on my new Pony. I am not disappointed. Install was pretty simple and it sounds great! I was considering Steeda axle back but this sounds great with the factory mufflers! Very pleased.

This was exactly what I was looking for on my 2018 Mustang GT. The sound is perfect, not too loud.

Steeda X pipe
Over the weekend I took my 19' s550 to a local speed shop to get the x pipe installed. After a few hours it was ready for pick up and the first thing I did was started it up with the push start and right off you can tell the difference in tone (and that was with a warm start) on the hwy it sounds great! You won't be disappointed at all even with stock mufflers. You can feel a little bit of power with the resonator delete for sure. Don't really need an axle back if you're looking for a sound that's not Obnoxiously loud to wake your neighbors up lol. This is the route to go. Great job Steeda!

Easy installation. Sounds great. Make sure and listen to the difference between the x pipe and h pipe in the product videos. That way you get what you want.

Great Sound - Needs pro install
This is a great X-Pipe that sounds awesome once installed. I think of myself as a DIY auto guy, and can do most things myself. Even though this seems like an easy install, I went with a professional shop and they did a great job. However, I own a 2018 Convertible Mustang, an d they had to make some cuts and welds to the X-Pipe. The directions state you only have to cut the exhaust, but the angles did not match on my car, so they had to cut both. Other than that, love it....

Steeda 2018-19 x pipes
Firs the staff ensured I got the right x-pipe for my 19 gt. I know the design is slightly different than the 15-17. It worked flawlessly. The construction was great, price was awesome and install was quick. I had a 2015 gt with a significantly more expensive cut and clamp x pipe and this one was just as high of a quality product and easy to install. Would recommend for anyone looking for a little more noise and tone on their 2019 mustang gt without active exhaust.

2018 GT Steeda X pipe
I purchased Steeda axle back and this x pipe together. I installed the axle back first and was so in love with the new sound that I left off the x pipe becauseI was afraid to ruin the sound...until recently! I finally got the courage to install the steeda x pipe yesterday and damn I love this thing!! Paired with my steeda axle back it made a world of difference. I think it's the perfect balance of loud af yet not in an obnoxious way. Install took me all morning but I procrastinated quite a bit as I wanted to be sure where I was cutting. So much easier dropping the whole exhaust system and cutting while off the car rather than underneath the car lying on the ground! Did the install by myself with ramps under the rear tires. I can't imagine anything sounding as good as the steeda x pipe with steeda axle back for the price!!

Sounds Glorious on my 2018 GT
It took the speed shop less than an hour to install. I'm sure not needing to worry about the heat shields helped. Getting on the throttle sounds great!
