    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!

      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.

      Sounds Great!

      My Stang finally sounds like it has balls! Install wasn't bad at all. I just unbolted the hangers over the stock mufflers, slid them on the Roush mufflers and reinstalled. ~90min, garage floor, on my back, neighbor yacking away. Now I can't stop cracking the throttle going under every overpass. It will stay quiet when you want to. When you lay into it, the car now sounds amazing. I particularly love the pops and crackles when you let off the throttle. It makes me smile every time. 10/10 would buy again.

      You have to buy this!

      First mod I bought for my 2014 GT. I got a shop to install it because I didn't have the right tools/jacks. It makes the stang loud and aggressive. Cold starts are amazing. But the best part is punching it to about 3500-4000 RPM. It makes this awesome crackling and loud rumble. It's amazing. Idle is low when stopping at red lights, but once you barely press on the gas it roars to life! It is pricy, but it's worthy every penny!

      Very happy with the purchase! Sounds subtle at idle, and wails when you want it to. Switched from the Magnaflows to these, and couldn't be happier!

      Worth the money

      I had some GT500 mufflers on before I purchased these and the difference was huge. I’ve always wanted this axleback and I can say that it leaves me with a smile every time I turn my car on. Best axleback on the market!

      Love the sound!!!

      I wanted something to give my car more sound from factory but not to be to loud as a straight pipe and this exhaust really did what i wanted. Its tamed when cruising around but loud when you get on it! Only reason it took an "afternoon" was sense i took off my stock mufflers without messing with the midpipes

      Can't believe how much more amazing it made my 2013 5.0 GT. I thought it sounded good with the mufflers that were on it but the Rousch axle-backs extremely easy to install and made a world of difference. I love them!

      Best decision ever

      Absolutely exactly the way i was looking for my 5.0 to sound! I love how it sounds in all aspects, in idle, WOT, and inside the cabin. Really wakes that coyote up! I literally ride around with a smirk lol ;) Took me, (a professional tech,) about 45 mins, and a coworker towards the end to help align them to install. Pretty simple bolt on application.
