They sound raspy past 3,000 rpm but an intake and shorty headers will deepen the tone a bit and you can also add a cheap x pipe and dynomax race bullets to deepen the tone ever more. That's the closest you'll get to a v8 but it will still be a mile away from sounding like it.. The unique tone that I'm talking about is like a GTR. Also if you buy these it's an easy install. You won't find an exhaust that sounds like this. For warning if you have a v6 mustang don't do a cat delete because it's completely a nasty raspy cringy roar past 2000 rpm. **Q: Will this fit an automatic?** A: Yes, the exhaust fits manual or automatic transmission 2011-2014 V6 Mustangs. **Q: how much HP increase using roush axle back exhaust ?** A: This system is more for exhaust sound and looks. Axle-back systems do not have large performance impacts. It will relieve exhaust back-pressure and allow the engine to "breathe out" better. How much that helps is case-by-case. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sounds amazing, easy to install. *by A***Y on September 25, 2025* Installed on my son’s 2013 v6 mustang.

Better than I expected and I highly recommend. It arrived before stated date. I had it installed by a great auto shop and only cost me $120. ### ⭐⭐⭐⭐ Amazing value, great sound! Not too loud. *by A***N on September 28, 2018* Arrived a day early, although I'm sure that will vary depending on where you're ordering from. Sounds amazing! If you short shift, it wont bother your average Joe but when you take it to 3k rpm, it makes the perfect growl, and anything above that has the potential for amazing backfires in 2nd and 3rd gear. I gave a 4 star review instead of 5 because it was advertised with black tips but came with chrome. Not a big deal to me but still false advertising. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1380980-2011-2014-mustang-roush-v6-3-7-axle-back-dual](https://www.desertcart.tn/products/1380980-2011-2014-mustang-roush-v6-3-7-axle-back-dual) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-08*
