Product Description

Roush Rumble
Add an aggressive exhaust tone to your 2015-2017 Mustang V6 or EcoBoost with this Roush axleback exhaust! This innovative new exhaust system from Roush features a hollow muffler chamber, as opposed to conventional fiberglass-packing. The result is a unique and less inhibited sound for your 3.7L or 2.3L engine with increased air flow, and increased longevity (there is no fiberglass that will break-down with time). Another great feature of this 2015-2017 Mustang Roush exhaust system is the lack of the in-cockpit boom normally found with performance exhaust systems at cruising speeds.

Top Notch Quality
Not only does this exhaust sound good, it looks good as well. The round tips are made from high-quality 304 stainless steel and are finished with a chrome flashing process. Conventional chrome plating uses layers of bonded chemicals to achieve its shiny appearance, which are susceptible to cracking and flaking especially when exposed to high temperatures (like exhaust). However, the chrome flashing used in this system is bonded micro-porously to the metal surface, and is as a result impervious to cracking from localized damage. This method of chroming is also resistant to heat color change.

5 Stars   Roush breathes life into Mustang
By on 2/11/2015
Image uploaded by Mustang Dan I got a 2015 Mustang V6 automatic and the factory exhaust only sounds good when you first start it, after that boring. I washed the car and cut my finger on the factory exhaust tip because it is thin and cheap. After I had the Roush kit installed, the Pony came ALIVE! The tone is deep at start up and when taking off from a dead start. As you excelerate the tone gets even meaner ( in a good way). The quality of the tips are superb. The chrome is bright and they are heavy and smoothe at the ends. Roush axle-back exhausts added new excitement! It's fun to rev-up! I almost look foward to stopping at red lights, so when they turn green, I can get on it!

Yes, I would recommend this item to a friend!

This gives an aggressive sound to your S550. Especially on cold starts, you get a rush of excitement each time you turn your Mustang on. I love this exhaust.

2 Stars   Horrible Drone at 1500-2000 RPM
By on 5/6/2016
I purchased these from LMR based on so many reviews (here and in other places) that indicated there was 'no drone' or 'very little drone' with them. I just had them installed on Tuesday at a local custom muffler shop and the drone in the 1500-2000 RPM range, when the engine is under load is definitely a problem. I am not particularly sensitive to low frequency sounds but I find the resonance created by these mufflers to be pretty annoying. At this point, I'm trying to figure out if I can live with them, or if I will need to go back to the stock mufflers. They sound absolutely fantastic when starting up, accelerating, or cruising when the engine isn't under load but if you are cruising and the engine settles into that 1500-2000 RPM range, it's enough to give you a headache.

3 Stars   Roush Let Down
By on 6/23/2015
LMR came through, whereas Roush fell on their faces.
The passenger side muffler was for a GT and obviously un-installable. There I was with my car up on jack stands and only one muffler. I contacted LMR and Trey helped my out. Roush I understand was a no show as far as customer service is concerned. LMR sent me a new muffler replacement while my car sat on jacks for over a week. I had to scrounge a ride to make it to work and back.
Thank you Trey and LMR for supporting your "fell on our face" vendor Roush.
I would purchase equipment from LMR anytime. Don't know about Roush though.


Yes, I would recommend this item to a friend!
