Description

For Louder and Deeper Tones. This Roush Axle-Back Exhaust with Black Tips, which is designed exclusively for American Muscle, is designed to produce louder and deeper exhaust tones. It features a healthy rumble at idle, which builds to a powerful roar when you step on the pedal. Enjoy a drone-free experience inside your Mustang’s cabin, while you get powerful and aggressive tones outside.

Enjoy Maximum Performance. Get the best out of your Ford Mustang GT with this Axle-Back Exhaust upgrade. Featuring full mandrel bending, this exhaust assembly offers a constant inner diameter without any kinks or creases for that smooth performance. The assembly is also designed with reduced back pressure in the system and improved exhaust flow. As such, you get increased horsepower and maximum performance.

Exceptional Quality. Designed for guaranteed performance and long-lasting service, this exhaust assembly is comprised of high-quality components. From the mufflers to the equipped mounting clamps, these are all constructed from corrosion-resistant T-304 stainless steel material. The tips are 4-inch, black, dual wall tips, which are unique. You can rest assured that this exhaust assembly can withstand years of abuse and still look great and perform like new.

No-Welding Installation. Getting this axle-back exhaust mounted to your Mustang requires some cutting. You need to cut through the factory muffler and tip assembly so you can slide in the new ones. No welding and drilling needed as you will use your vehicle’s factory hangers and mounting points.

  1. Jesselv

    Easy install, definitely a nice sound to the car. Running stock resonator still so it’s not too loud. All parts showed up, so no complaints.

  2. Rough

    Great product and easy install. Increased exhaust loudness with Ford performance exhaust on GT. We are very happy with the product. Black tips add the touch if you have blacked your vehicle.

  3. Trevor

    Best sounding exhaust in my opinion !! Such a deep raspy rumble. I get compliments on it constantly!!

  4. Bloodycoyote

    Sounds great! Loud enough when you step on it and pretty quiet when idling. Sounds great! Pretty easy install too if you have a sawzall on standby.

  5. Sam

    Great product. Sounds amazing. Easy install at home in the garage. Thanks GEEK!

  6. Bigchef

    I love the way my Stang sounds with the Roush Axel Back . exhaust. Loud when you crank it up and get on it yet fairly quiet with no drone when driving on the highway. I installed the Roush Axel back exhaust and Roush X Pipe at the same time and in my opinion it gives my Stang the perfect sound.

  7. Dan

    I have always went with Roush My 2006 2014 2015 and now 2017 have always had them installed within the 1st week

  8. Edwin

    Amazing exhaust paired with H pipe and vibrant resonators almost 0 rasp best exhaust out there sounds so sexy you will have an eargasm

  9. Jon

    Great sound. Easy to install. Took less than an hour. Instructions were great just need a saws all and some wrenches

  10. Maximizer

    As a convertible I didn’t want to make it obnoxiously loud and ruin the top down experience and go deaf. This is the perfect balance of being JUST loud enough so that it is definitely NOT too loud, and definitely NOT too quiet. It is loud enough at cold start but not enough where any of my quiet suburban residential neighbors have complained. Vastly improved my ownership experience and is a real joy especially at 3K RPM+ and is plenty quiet below that. If you have a black Mustang like I do, get the black tips like I did!

  11. Louis A

    I was very nervous at first when choosing my axlebacks mostly because of neighbor complaints. But I really wanted something that brings out the coyote’s power through sound and roush axlebacks are the perfect fit. These axlebacks are amazing. Yes they are amazingly loud when you step on it. Quality is amazing, they are true to there products quality. And overall an easy installation, took probably about 20 to 30 minutes to install. Loving them alot plus the black tips do look amazing for the black coyotes.

  12. Jack

    I had the factory exhaust removed and the Roush axle back installed. I have noticed an increase in power and performance along with the Air-Raid cold air intake, plus with the VMP tuner, and tune sent by geeks. Thank you guys for the great products and excellent customer service and support. 2016 Mustang GT 5.0 Coyote

  13. Chapstick

    I combined this axle back with the corsa 2x pipe and god mf damn it goes crazy. Anything above 2k rpm it really starts to purr and then once you pass 3.5-4K rpm it screams. The very best part about it is that when you are under 2k rpm it stays relatively quiet, it’s still loud but not fix-it ticket loud.

  14. JeffOwens

    Sounds great!. Although I did not purchase or install the Roush axle-back myself as it was already on my Mustang GT 5.0 when I purchased it, I can say it sounds awesome! It is one of the main reasons I purchased the car. I have the six speed manual and this makes a great sound going through the gears for sure.

  15. Cyclonecjtrev

    The Roush Axle Back Exhaust set up is a great option for people like me who want a louder and depose exhaust note than stock. My set up is paired with a resonator delete on my 5.0 mustang and pops like popcorn. The install was quite easy as well if you have the right equipment.

  16. Patrick120

    Installation was easy and the product looks great. Fitment was easy to align and the sound is great. No drone and still quiet in 6th gear which makes this a good balance.

  17. Prince

    Easy to install and sound great with the Roush H pipe

  18. Jcoombs

    Recently installed on my 2017 mustang GT. Definitely gave it a deeper raspier sound, would recommend if your looking for a little more aggressive sounding exhaust, but not trying to wake your neighbors every morning when you start it up. (Just be sure they send you the clamps when you open the box. Mine were missing and not much was done about the situation.

  19. Metroidcorrupt

    Bought this for my partner, for his 2017 mustang GT. Installed this exhaust in about 10 to 15 minutes and literally such a big difference. Probably best mod we have purchased for his car so far. I just bought the 2020 mustang GT with the active exhaust and he gets more public comments on his exhaust then i do on mine.

  20. Anthony

    Love the sound of my Roush axle back exhaust. Probably my favorite ??exhaust. American muscle did send me two drivers side exhaust but I did made one of them work for the passenger side. Other than that two thumbs up ????

  21. DAWilson

    I wanted my stock 2017 GT louder but not obnoxiously loud. The Roush Axle-Back did the trick exceptionally. It basically amplified the sound in a very awesome way. Now my car sounds like the mustang it is. At low speed its quiet like stock but press the gas pedal and it makes me smile. It’s perfect! I won’t need anything else like the Roush x pipe I was considering if the sound did not meet my expectations.

  22. Stevenk

    Everyone’s know they’re on top… I delete resonator. and now I have h pipe with roush axle back exhaust with black tips. They sound really loud

  23. Don T

    By far, in my opinion the best sound for your Mustang! I have a convertible so was a little worried it might be too loud but it is perfect. You here it when you accelerate and it rumbles a little when you slow down.
