Has anyone installed the Roush Performance Exhaust for the 2010 Mustang GT? If so, what do you think of it?

And, why do it say "For Off Road Use only" on the installation instructions?

 

It says for off-road use because it basically eliminates the rear mufflers, I believe they have resonated tips instead and it is fairly loud.

You can find some clips on youtube for the exhaust and the blower.

 

I have that exact system installed on my 2010 GT. It has resonators in the mid-pipe after the H-pipe snd then no restrictions all the way to the tips. It is loud.... sounds great at idle, fantastic at WOT or just cruising in town. It does have drone at about 2K to 2300 rpm that can be annoying on the highway. With the 3.73 gears I am in the drone zone between 75 to 80 mph

 

Where did you get the GT500 wheels? Those look awesome. Is there someplace I can pick them up at a decent price?

 

You can get them on ebay but the prices aren't generally too decent...

American muscle offers repro's of them.

 

Love my roush exhaust ! It makes driving my GT even more fun. I love the way it burbbles .

 

Does anybody know if i can out my slp loudmouths through my roush squared tips without messing with the sound?
