Does your V6 Mustang Exhaust ROAR?

Well it's about time to give your ride the aggressive sound that it deserves with the ROUSH® V6 Mustang Exhaust Kit.

This kit fits 2011-2014 V6 Mustangs and features a all-new ROUSH open-chambered muffler with round tips. In contrast to the conventional fiberglass-packed muffler design, this open muffler has a less inhibited sound, increased longevity (because there is no fiberglass packing that tends to break-down over time), and increased air flow for maximized power. Another great feature of this system is the elimination of the in-cockpit boom, which is common in performance exhaust systems at cruising speeds.

Quality Construction
The round tips of this Mustang dual exhaust kit are made from high-quality 304 stainless steel. The shiny finish of these tips are made with a special chrome flashing process that is dramatically more resistant to cracking and flaking than conventional chrome surfacing. The mufflers and inlet pipe are made from 409 stainless steel for improved durability. We stand behind the quality of this kit with a 3 year limited warranty.

**ROUSH Performance recommends checking your local noise ordinance levels prior to purchase.

This V6 Mustang Exhaust kit installs quick and easy. It uses the factory hanger mounting points -- you don't have to fabricate your own. This kit also features spherical OE-quality clamps for a perfect fit.

Please also note that this kit has no negative effect on emissions.

This exhaust sounds MEAN! I wish it sounded exactly like the V8 GT exhaust, but I guess thats a little unrealistic. It definitely turns heads when I zip past people.

Loud and Proud!

Wow! This exhaust rumbles! I love it! I took it to the dream cruise and it was a huge hit. I had Flowmasters on before but I dented them in on a speed bump, so I replaced them with these. Very happy with my choice!

worth the extra bucks

This exhaust is awesome! Its a little bit price compared to other V6 exhaust kits (thats why I gave it a 4/5 stars), BUT it is definitely worth it if you can afford it.

Great sound -- very close to V8 sound. I'm 70 and it makes me feel like a 30 year-old again. Sounds awesome with the top down on my convertible.

These pipes look, sound and fit very nicely on my 2012 Mustang V6 Premium. I had a local Ford dealer install them and they aligned nicely to the center opening and in less than an hour. Great sound! Not exactly V8 quality ... but as close as it can get. (And you can control the sound somewhat my acceleration and shifting!)

Best Axel Back Kit for the V6 By far!!!

Just had these installed at a local shop this morning and the difference from stock is undescribable. There is a low bassy rumble at start up and up until about 2500 RPM's. Then after the 3000 mark, these monsters howl like an exotic sports car. They are definately head turners. Hardly no noise at all when crusing around 60-70 mph which is nice. Just a sexy rumble while under load until about 2000rpms which my wife loves, and when you punch it watch out, its a pure music to your ears. You will not regret purchasing this kit. I'm smiling from ear to ear while writing this and cant wait to get back in it to go for another drive. Just quit watching all the other you tube videos and buy it, this is the one!!!

Quick and simple install. Sounds AWESOME for a V6

A buddy and I threw these on my 13 Mustang V6 in right under an hour using 2 jack stands, a jack and hand tools. Very easy to hook up and the sound difference is amazing. Very impressed with the results.
