The Roush axle-back mufflers give my GT-500 the growl it deserves. At idle and through first to third gear at speed it rumbles with a rich throaty sound that is pure music. The only thing that detracted ...

Hello, I was wondering if the square tips would change the exhaust sounds in any way? Thanks!

  • Not really, the sound is primarily the work of the mufflers and the square/flat tips are more for appearance purposes.

I have a 2014 Shelby gt500 all stock. I'm looking to order the Roush Axle-Back dual chamber tips. Wondering is it necessary to change the rear valance or will the stock valance work with.

AlvinM

  • Hello! For the Roush Axle-Back Exhaust w/ Dual Chamber Tips, you will need to change your rear valance to a roush rear valance. http://www.americanmuscle.com/roush-rearvalance-1314.html

roush rear valance for 13 mustang gt Hi I am interested in the roush valance...I have a roush axle back exhaust but its not the flat tip one. Will mine work?

Blessedchef

  • You can buy the valance and square (flat tip?) tip. Once you've installed the valance and add the tips, you should be good to go.

    Growl

    The Roush axle-back mufflers give my GT-500 the growl it deserves. At idle and through first to third gear at speed it rumbles with a rich throaty sound that is pure music. The only thing that detracted from the install was the Roush approved rear valence. It doesn't fit ! The stock rear valence fits perfect with the new rectangular exhaust tips. Other than that the install went smoothly, only about 90 minutes. All in all, I'm very satisfied.

    Roush axleback exhaust

    This exhaust set up was worth every penny! Sounds like a beast when you hit the gas and no drone on the freeway! If you want a nice exhaust note and want to be able to listen to the radio this is the set up!

    Roush axleback

    This exhaust is probably one of the best sounding that I have had on a mustang. It's not obnoxious but is loud enough to let people know you are coming. The hardest part was installing the valence that was big enough to clear the exhaust tips.

    WOW..

    To begin with, American Muscle is amazing when it comes to shipping and delivering, I bought my roush axle backs on Monday and they came in Wednesday. This set of axlebacks not only sound amazing but there is next to NO sound when driving with the windows up. Definitely not lacking on the volume on the outside though! I have the bbk after cat x pipe and it's an awesome combo. These only took an hour and a half to install in the driveway.

    Pure Happiness

    If you get Roush Axle-Back by it self, it's gonna sounds great but not loud. If this your thing then do yourself a favor and get 'em. now if you pair 'em with an off-road X-pipe, it's gonna sound very loud, like really really loud. Again, if this what you're looking for get' em. Let me tell about my set-up - Kooks shoty header - Pypes cat-delete - Maganflow x-pipe - and the Roush Axle-back. It's beautifully loud, I get compliments all the time. However, The drone is really loud. Especially 70 mph and up. I do believe these Axle-Back are one of the best in the market.

    Match Made in Heaven!

    My 2014 ROUSH Stage 1 looked the part but definitely didn't sound the part. I purchased this ROUSH axle-back to fill this void and found a match made in heaven! Not only do I turn heads now by looks, but people can now hear me coming! Every penny was worth it! Not only does it sound good, it also sheds a ton of weight over the bulky stock mufflers.

    Just Wow

    This is my first review and fitting it should be for the Roush dual chamber axle backs because I've wanted these for a very long time. They are also the first major change I've made to my Mustang. They are absolutely beautiful to look at. The pop and rumble on these are enough to make your toes curl and heart race from the sound alone. Combine that with the look and you've got yourself something special. If you have a bit more time and money, I recommended these over the regular round tip Roush axle backs. Get a friend or two who aren't shy around cars and take your time with it. Watch online videos on how to install it and you can save yourself a lot of money. Don't think about it, just buy them. You'll be glad you did.
