Product Description

Give your 2011-14 V6 Mustang the aggressive sound it deserves . 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, increased air flow, and increased longevity (there is no fiberglass that will break-down with time). Another great feature of this system is the lack of the in-cockpit boom normally found with performance exhaust systems at cruising speeds.

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.

As you would expect, the installation of this system is quick and easy. The exhaust uses the factory hanger mountings, so you don't have to fabricate your own. This kit also features new OE-quality spherical clamps for a better fit.

  Excellent sound!
By on 2/25/2014
I have had mac axlebacks and bassani exhaust on my 13 v6. They both sounded good but I wanted something louder. I wanted something that when I sunk my foot to the floor people would hear me coming. These roushs gave me that! They do not sound "ricey" like people say and I have loved every minute of them! What's really amazing is the lack of drone compared to how loud they are outside of the car. I have only had these on for a couple of weeks and have had numerous comments by others on how good they sound!

Yes, I would recommend this item to a friend!

This kit is awesome right out of the box, the craftsmanship it top notch, they fit just like factory parts, I have a 2014 and this was my first mod. They sound is incredible!! It really wakes up the exhaust tone, still sounds like a v6, but is not disappointing!! Only had it on for 4 days and have had several compliments none of witch were negative, buy far the best exhaust for the 3.7 hands down!!!!!

Yes, I would recommend this item to a friend!

I took my Flowmaster force 2 mufflers off and installed these and it was like night and day, these are a very loud muffler but I love it, I have BBK headers and BBK catted x pipe, cai, and tuned on mine, but when I first started car it was like I was just running open headers, you wont be disappointed buying these, they line right up, coming out the valance and they are very light.

Yes, I would recommend this item to a friend!

  Roush Axle Back Exhaust Kit (11-14) V6 3.7L
By on 7/21/2014
Ordered these for my Black Ford 2012 V6 Automatic Mustang. They are meduim loud I think. They sound good, but not quite like a V8. I didnt think it would but still make the car sound nice. I have to admit from time to time the sound does sound a bit like a rice burner. Im still happy with the purchase. I paid $100.00 to have a specialty shop put them on.

Yes, I would recommend this item to a friend!

Great product. Install was easy. They are very loud. Little too much drone around 2000 rpm, but over all, awesome exhaust.
