I have a 2011 roush stage 1 and I want to put quad tip exhaust on it. Has anyone out there tired this? I've seen them cut the oem rear valance but never a roush valance. I'm trying to avoid buying the 13-14 gt500 rear bumper and all that. If I could just cut the roush rear valance on the car and get new axle backs, that'd be ideal.

 

You can buy the '13-14 GT500 valance. You don't need the whole bumper.

 

I was under was under the impression that it wouldn't line up correctly with my bumper.

 

Is your bumper different from a stock GT bumper (besides the Roush valance) ?

 

I think it's the same. Whatever comes with the 2011 roush stage 1

 

I know on my '13, the factory marked out where to cut for the quad tip valance. I'm not sure how the '10-12's are set up. Since the factory never offered a quad tip system, I bet those bumpers are different.

 

You will need a bumper cover for a 13/14 model to use quad tips on a 2012.
