Mandrel bending maintains a constant inner diameter with no kinks or creases. This improves exhaust flow and reduces backpressure in the system. This system includes single tip High flow mufflers that improve the stock sound of the Mustang V8 This system will produce louder deeper exhaust tone, with a healthy V8 burble at idle, building to a powerful roar at high Review: Perfect kit if you want that deep growl from your Mustang! - This is an AMAZING muffler kit. I installed it myself in less than 90 minutes, which included gathering the tools needed and getting my '15 Mustang GT up onto a couple jack stands. I've never cut into an exhaust system before, but have used a reciprocating saw on numerous occasions, so it wasn't that difficult at all to prep the stock pipes. Just follow the instructions correctly and you'll be fine. There are a handful of videos out there on the web as well if you'd like to see someone else install the kit first before you do it. Roush did a fantastic job designing these and they fit perfectly. If I had to guess, I'd say that both of the mufflers weigh around as much as one stock muffler, so you're actually shaving several pounds off the car too. The chrome tips look great sticking out of the back of the 'Stang and are very stylish. The sound produced by these mufflers is GLORIOUS. My car is otherwise 100% stock (for now) and I am more than pleased with the tone. My car is a daily driver, so I wanted a strong, deep sound that would not sound obnoxious at idle or while cruising. The rumble from inside the car is very satisfying, especially under hard acceleration. I decided on an axle-back kit as opposed to a full cat-back system because I didn't want anything too extreme. If I ever change my mind down the road, all I need to do is swap out the stock resonator with an aftermarket H-pipe or X-pipe. For now, I'm really happy with how the car sounds. Finally, I have to say that Yates Performance has ridiculously fast shipping. I ordered this kit on a Thursday night and it was delivered to me by Saturday afternoon. I do live in a state right next to them (they're based in Virgina), but even so, receiving an order less than 48 hours after placing it is amazing. Great mufflers, easy installation, fast shipping. Buy this kit with confidence! Review: No drone and plenty of noise under acceleration! - Mufflers are exactly what I was looking for! Installation was easy, and everything fit perfectly. The tips look great, and the sound is awesome. I was looking for something that I could hear and feel. These mufflers with the stock resonator are quiet when cruising and on the highway. When I step on the gas they just open up and the exhaust howls! They scream all the way to the redline! I don't care about my music anymore because the sound of the exhaust has me driving with the windows down and ripping through the gears! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00SVE8IR4 | | Best Sellers Rank | #2,598,149 in Automotive ( See Top 100 in Automotive ) #103 in Automotive Replacement Axle-Back Exhaust Systems | | Brand | Roush | | Customer Reviews | 3.8 3.8 out of 5 stars (66) | | Date First Available | January 28, 2015 | | Is Discontinued By Manufacturer | No | | Item Weight | 29.9 pounds | | Item model number | 421834 | | Manufacturer | ROUSH | | Manufacturer Part Number | 421834 | | Product Dimensions | 26 x 24 x 12 inches | ## Images ![Roush 421834 2015 2017 Mustang GT 5.0 Axle Exhaust - Image 1](https://m.media-amazon.com/images/I/41oaPjM4EQL.jpg) ## Questions & Answers **Q: Is this California legal?** A: Yes, axle-back exhausts do not affect emissions and can be used in California. This system comes after the air intake system and catalytic converters, which do affect emissions. **Q: What's the noise level for this? Is it lower than 95 decibels, that's what it needs to be for California.** A: Ain’t this America? Brother you need to move to a free state. It idles under 95 decibels. It can get louder if you want it to be. **Q: Would they fit on a 2016 mustang ecoboost** A: Probably not. But why would you put an exhaust on an ecoboost? They sound awful when they’re loud. Maybe you should get on CJ Pony parts and look at exhaust systems. They have videos of installation and sound clips of what it will sound like so you don’t end up with something you hate. **Q: does the clamps come with ? and also the muffler tips?** A: Yes, clamps come for the muffler pipe and the included tips. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect kit if you want that deep growl from your Mustang! *by T***D on October 10, 2015* This is an AMAZING muffler kit.

Installation was easy, and everything fit perfectly. The tips look great, and the sound is awesome. I was looking for something that I could hear and feel.

The sound is amazing, way better then stock and it's the way it should of sounded from the factory for a v8. I had it professionally installed at a muffler shop. The right tip sags a bit more then the left one, about half an inch. He states that these never fit 100% even if it's from Roush... I thought he was crazy lol. I'll have him adjust and fix it next time I go in when I get my Roush X pipe... Yes I want it louder... --- ## 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.com.cy/products/12749832-roush-421834-2015-2017-mustang-gt-5-0-axle-exhaust](https://www.desertcart.com.cy/products/12749832-roush-421834-2015-2017-mustang-gt-5-0-axle-exhaust) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
