I replaced my roush's with gt 500's and my car says thank you! Feels like i gained 7 hp. Selling my roush's today to a guy with a 13 gt.

I am running the Borla touring AB. At least that is what it looks and sounds like. Came with the car when I bought it. Very quiet at idle when warm. The rest of the exhaust is stock. I did test drive a muffler shop special. Deleted the resonators & mufflers. All welded in. Sounded like crap. When I get on it it gives me very deep sound. I really wished I knew for sure how to tell if they are Touring or S type. They are so quiet at idle that I have decided not to buy the cam idle tune for mine. I do not think you could hear it. The most important thing to me is deep sound and no drone.

....and you won't be disappointed! Been running my Roush for 3 months and get compliments just about everyday. I'm tempted to add some high flow cats but afraid it might be to loud.

Beautiful car. I have performance white also and haven't touched the exterior because I don't know which way to go with it.

I have really warmed up to the GT500s. Seems like they got just a little louder as time has passed. I still plan on having the resonators cut out but I'm in no hurry to do it. All in all I'm very happy with my purchase especially since I picked them up used for $175 shipped. It's really the closest I've heard a S-197 sound to a SN95. Just not as much volume.

I bought my Roush axelbacks right after I got my car, took it to a new place to get washed over the weekend and a fellow mustang owner had to know what I had done and where he could get the mufflers.

Love those freaking things sounds so mean.
