    Aggressive Raspy Sound. Designed for 2018-2019 GT Mustangs that are not equipped with the factory Active Exhaust, this Roush Axle-Back Exhaust will let everyone know you have arrived with its aggressive raspy sound. This innovative new Roush exhaust system features a hollow open chamber muffler that results in increased air flow and a unique sound, with no in-cabin "boom" normally found with performance exhaust at cruising speeds.

    Quality Roush Construction. Roush manufactures their exhaust systems from mandrel-bent 304 stainless steel for durability and corrosion resistance. This Axle-Back Exhaust features two unique open chambered mufflers that improve exhaust flow. The system includes two dual wall 4 inch quad tips that are finished in a new chrome flashing process that is resistant to exhaust heat discoloration.

    Cut & Clamp Installation. The installation of this Roush Axle-Back Exhaust will require cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps and instructions are provided.

    Application. This Roush Performance Axle-Back Exhaust System is designed to fit 2018-2019 GT Mustangs that are not equipped with active exhaust from the factory.

    Can I just get the roush dual exhaust tip?

    • Unfortunately the Roush quad tips are not currently offered separately.

    Is this 2 1/2" tubing or 3inch?

    Will this fit on the "16" GT Premium. I already have the Roush axle back single tip. Want to change to quads.

    • These are for an 18-19 GT Premium. The Roush exhausts that you would need are: (https://www.americanmuscle.com/roush-quad-tip-axleback-2015gt.html) You would then need the Roush lower valance to work with the quad tips. That item can be found here: (https://www.americanmuscle.com/roush-rear-valance-noholes-1516.html) or if you need pre-drilled reverse sensors: (https://www.americanmuscle.com/roush-rear-valance-2015.html)

    Your loudness level graphic shows higher for the black tip system than the chrome tip system. I assume these are the same mufflers and the two actually sound the same? What is so different on the black tip besides the price that makes it way louder on your loudness level?.....Thanks

    • The exhausts will included different mufflers. This exhaust includes an open-chambered muffler design while the black tip exhaust will include dual high flow mufflers.

      Loud outside but too quiet inside

      The exhaust is crazy loud outside but i did not like that the car is very quiet inside its way more quiet than stock inside so now i dont even know if im going to keep it or sell it also another thing i did not like is that the exhaust tips are way to small for the car so they look kinda wierd

      Sound Great!

      I bought this exhaust set for my wife for Christmas... She loves it! I had my buddy at our local muffler shop install it. It took them about 45 mins. He installed it for free when he found out she had gotten it as a Christmas present.

      First mod for my new S550

      Ordered this exhaust from AM on a Wednesday and got it today (Tuesday). Everything boxed securely. Cosmetic finish of the setup is good. The welds look OK a little chunky and splattery but of course nobody sees the welds when it’s installed. The tips are nicely polished and have the Rousch ‘R’ lightly white laser etched an inch tall on the left side of the left tip set and right side of right tip set so it shows when installed. Rousch is also stamped on the bottom of each muffler, Two Rousch decals included in the box. Installed after putting the car on jack stands. Note if you’re doing it on stands there is very little clearance for the sawzall and blade so you’ll have to cut the pipe from the bottom up. Cutting the stock exhaust off was easy with a carbide Diablo sawzall blade. Took at most 10 seconds per side after finding the right spot to cut. Both mufflers slipped into the rubber isolators and into the cut exhaust stubs with ease. 3/8” impact driver with 15mm deep drive socket was plenty to get them secured. Tips fasten with the same size clamps and weren’t too hard to get on straight. When looking from the back the tips look like they hang low but it’s an optical illusion. The tip material is thicker than factory and the inner diameter looks a little smaller. They have the same drop as the factory ones. Total job took 40 minutes but I do similar work daily so plan for 1.5 hours if you don’t do much work with tools. This was my first modification to my PP1 ‘18 GT. With the resonator still installed it really wakes up the sound just to that perfect sweet spot. This is my 80 mile commute daily driver and on the way to work there is less cabin noise than factory cruising at 70-80mph. But get it over 2K RPM’s and you’ll really know it’s there. Get it over 5K rpm and it screams how you want it to. Overall the sound is cleaner, more pronounced, but not excessive. Deeper bass tone than factory, more rasp, some extra pops when revving and downshifting. Definitely recommended if you like the stock exhaust sound, but you want more of it. This is the loudest I would personally want for a daily driver. Would recommend and buy again. Thanks AM and Rousch!

      Axle back what?!?

      I wanted to dump the stock boat anchors. Didn't want to spend to much as I don't know what I want to finish with in terms of performance. They came in two days, free shipping. Took less than an hour to install. The sound is perfect, silent at cruise, no drone. Running around town you can tell the difference. Also I swear the car is noticably quicker and revs a lot faster.

      Shoeless

      Pretty quiet when off the pedal with a lower more aggressive growl. Comes alive with the throttle and earns that 4/5 on the wake the neighbor scale. With my son the install took 30 minute with a lift and the finish is perfect.

      Rrrrroush!

      Measure 4 times, cut once, slip on, clamp and Rrrrroush! Awesome sound, easy install and great fitment. Only slightly louder than stock while cruising but open it up and enjoy the amazing noises. A lot of fitment issue reviews concerning low hanging tips but none here. Make sure your cut is in the right spot and twist the piping upward and hold it there before tightening the clamp. H-Pipe awaiting install although the axle-back alone is perfect.

      Very happy with this setup.

      I love this setup. I was concerned about getting a system with dronning, but it does not. I wanted a system that would add some sound but no drone. I love the deep rumble sound and it will scream if you want it to. The 1 thing I wish was better is moving the tips up a bit. They hang down a little more than stock. Roush is stamped on the muffler but not the tips. Nobody will see the muffler and everyone will see the tips.

      Love it!

      Installed these on my 2017 GT. Just needed to bend the hangers out about 1 inch then it fit perfectly in the MP concepts 350GT valence. An acetylene torch helped with bending the hangers since they are fairly thick SS rods however it can also be done without a torch with 2 people and a 4 ft. pipe I couldn't be happier with the results. Love the sound and the look is exactly what I wanted.

      Great sound for the price

      Fantastic growl at higher rpms and low, deep tone at the lower band. I used less than ideal tools to cut the exhaust pipe and ended up taking longer than it should. If you cut the pipes correctly, this should take 30 min to install.

      Great exhaust, but not perfect

      Great sounding exhaust and easy install. But like others have mentioned, the exhaust tips simply hang too low. It is possible to bend the hangers for a better fit, but they are quite strong and difficult to manipulate. This is an unecessary hassle. For a brand like Roush at this price point, the product should fit right out of the box....

      Great sound, deep tone, very loud but....

      The Roush axle-back exhaust is a go to for anyone looking for a deep roaring sound out of there Mustang gt, the only flaw that I did come across was that I received 2 driver side exhaust tips rather then 1 passenger and a 1 driver side. Besides not receiving the correct parts, installment was super easy, sound is great and it brings the car alive, especially with a H-pipe cut and clamp. Highly recommend this Rousg axle-back setup.
