The Ford Mustang Exhaust Extreme Performance Kit gives your Mustang that rumble sound letting other's know you mean business while increasing the horsepower and torque of your vehicle.
The increased power is generated due to the higher flow system as compared to a conventional exhaust system. Yet another benefit of this high flow system is that it improves fuel efficiency, as the engine runs into less air resistance to do its work. Fits 2005-2009 Ford Mustang GT/GT500
Though this particular exhaust for the Ford Mustang creates more sound outside your car, it doesn't create the typical off-road exhaust drone inside. This is made possible because sound is more effectively directed backward through the exhaust system and out through the rear of the vehicle.

The exhaust system is manufactured using a CNC bender to create smooth mandrel bends. This process maintains a consistent inside diameter through the bended area and allows for a significant increase in flow over stock/serrated-bent pipes.
This Ford Mustang exhaust kit is made from high-quality 2.5-inch diameter stainless steel tubing and has 4-inch diameter tips made from polished 304 stainless steel and embossed with the "ROUSH" logo. The system comes with OEM stainless steel exhaust clamps that provide a leak proof seal and won't smash or crush the pipes when tightened.
The ROUSH Resonator Off-Road Exhaust Kit fits 2005 - 2009 Mustang GTs and GT500s with factory rear fascia.

Great sound and performance
By Gary Dickhaut August 31st, 2012
I have a 2007 GT convertible. After this exhaust was installed the comments from every car enthusiast are WOW GREAT SOUND! and what has been done to the engine besides the exhaust. I tell them the engine is stock, however, you wouldn't guess that from the increased power on acceleration. It gives the 4.6 a deep rumble that you won't believe. The great sound doesn't reverb throughout the interior and at normal driving speeds and acceleration you just hear a nice deep, smooth exhaust that isn't too loud. Then speed up a little and the sound comes out and turns heads, put the pedal to the floor and all heck breaks loose and the ROAR is nothing less than what you get from straight racing exhaust. It's very well made from top grade materials. I can't say enough good about this.
Exhaust sound, performance, shipping.

The sound alone with stock h pipe and headers is absolutely brutal, if is extremely aggressive but has a deep sound at the same time, it will vibrate your floor board a little.. which makes you feel pretty good when you mash on the gas. the sound clips do not do the product justice, as it sounds much louder and better in person. the resonators kick in when your in a higher gear and lower rpm.. making it quiet on the interstate. as for performance,, i don't feel the hp gain, but i can definitely feel the torque, i can feel the engine breathing. Over all its the best sounding exhaust ive ever heard that's legal, and installation took 1.25 hours with an impact gun.. the pipes line up perfect and installation is easy!!!
