    Review & Install Video

    Hey everyone I’m Justin with AmericanMuscle.com and I’m checking out this Roush axle-back exhaust system for all 2011 and up GT Mustangs. This unique axle-back design from Roush features an open chambered muffler, which allows for a more aggressive exhaust note, while keeping drone to a minimum. The system is constructed from 100% stainless steel and features two chambered mufflers and two four inch stainless steel polished tips, both inscribed with the Roush logo. Simple bolt on installation should take you no more than an hour. Let’s hear how this axle-back compares to the stock exhaust.

    Aggressive Muscle Car Sound. Let your engine howl with a Roush Axle-Back Exhaust. This innovative new Roush exhaust system features a hollow 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. Constructed from 409 stainless steel for a durable long life, the Roush axle-back exhaust system features two unique chambered mufflers with 304 stainless steel 4" tips. The 4" tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

    Application. This Roush Performance Axle-Back exhaust system will fit the 2011-2014 GT & 2011-2012 GT500 Mustangs with either the factory GT rear valance or the Roush rear valance.

    What exhaust to buy? I'm looking for an axle-back exhaust that is one notch above stock in terms of sound. I don't mind WOT loud, but at normal acceleration, idle, and cruise I want just a little more growl. I still want to listen to music and carry on a conversation typically. What exhaust do you think fits the bill the best?

    mbrewer566

    • This would be the best exhaust for your needs. I installed it on my vehicle and the sound is perfect! It is not loud and obnoxious when you are just driving normal, but when you get on it you can certainly tell a difference. This is the best bang for your buck, and has the best sound!

    Will the Roush Axle Back tips be flush I've noticed on the '13 models alot of the aftermarket axle back tips stick out vs being flush with the plastic. Is the Roush flush?

    tjb144

    • You can adjust your tips however you like. Flush, outside the valance or in. I have mine sticking out a bit so you can read the Roush name on them.

    Is it necessary to purchase the valance with this roush exhaust I am interested in roush exhaust; however, I prefer without valance. Is that possible?

    Ruby

    • Absolutely! You would just Add to Cart without making the selection under accessory options for the Rear Valance. This would only add the Roush Exhaust to your shopping cart. You could also give us a call if you'd like us to place the order for you!

    I have a 2013-2014 GT500 rear valence and quad exhaust on my 2013 Mustang GT..You think its possible to install aftermarket quad exhaust tips on this Roush Axle-Back Exhaust instead of the just the single tips?

    PatrickD

    • You would be able to install an aftermarket tip on the Roush Axle-Back Exhaust, however we are unsure if a quad tip would clear your rear valance with this axle-back.

    I had the Roush catback for the 05-09 GT is this a pretty similar sound? Or would I need to get a H-Pipe or X-Pipe?

    Erik

    • The Roush Axle-Back Exhaust will have that signature Roush sound still, however, they will sound different due to the different motors in those years.

      Awesome Exhaust

      Great system. Need to do this on a car lift, not on jacks!!!! Thank God I had access to a buddies car lift. Install cat backs first, then the exhaust. Unlike the directions say. Increases a noticeable low end torque without a tune You will love this system, low rumble under 2500rpm. When you get on it, Heads turn everytime!!!!

      Excellent quality, great Roush sound with no droning especially on freeway and would buy again. Sounds awesome at cold start and around town. Installation was not fun bc had to remove midpipe which I didn’t expect whereas with other axlebacks simply slipped them on, but it was worth it in the end and was smiling out of excitement!

      Great rumble

      These sound amazing. I found they are decently loud but definitely not overbearing... My Gt actually sounds like a mustang now. Took me right around an hour because the stock pipes took awhile to get off... I'd say I had them installed in 15 min from the time I had the stock pipes off

      Worth the money

      I am very happy with tje sound of these mufflers. Makes my 14 gt sound the way it should. I noticed a slight bump in mileage (nice suprise, i wasnt expecting it). Not stupidly loud, but a nice healthy rumble. No drone at highway speed even with the top down.

      Perfect!

      This exhaust rocks! Loud when it's supposed to be and very little drone. If you don't like this exhaust, you shouldn't be driving a Mustang. On my Mustangs, I've had the American Thunder and the Flowmaster catback, the Roush axleback is perfect if sound is what you are after. Constantly complimented on how it sounds. Trust the reviews, this exhaust sounds awesome!

      Roush axle back

      Love it... The sound is amazing... Install for me was way faster than reviews. Too 35 min start to finish I didn't remove the mid pipe and I used jack stands rachet you'll need 1/2 inch and 14 mm... Done. Trick for the rubber gaskets spray some oil penetrate makes it 100 times easier. Worth the money btw freaking amazing.

      TOO LOUD with POPPING and DRONE SOUNDS

      I gave these exhaust 2 stars because they look good with Roush logo on the tips. They look nice as they are round and fit better underneath the Mustang than the oval stock exhaust. I think American Muscle misrepresented the sound of these in the their online ad with Justin Dugan. Out of the 3 exhausts he tested, he ranked the Roush as the median sound of the 3, Borla was considered mild so I wanted the middle of the road rumble! NOT LOUD DRONES and Sound like the vehicle was missing?? I had the stock exhaust put back on!! American Muscle didn't care about the situation!! UNHAPPY with American Muscle!! There are so many good parts companies it is not a problem!! My 2013 Mustang GT has 11,000 miles on it.

      Great sound for your 5.0

      I had magnaflow race with resonator delete previously and it was too loud. Installed these beauties and it looks and sounds amazing. Fit and finish are always on point with Roush and AM had them delivered lightning fast. I rated them at less than an hour for install however, if you have stock exhaust it will take a bit longer to get them off. Make sure you use something like PB Blaster and you’ll be fine. In conclusion, I absolutely love these Roush axle backs, no drone whatsoever.
