I had the Roush cat-back on my 10GT. I got compliments every where I went. I wanted to upgrade more and purchased BBK long tube headers and a BBK o/r X. Combined with the Roush system it is WAAAYYYYYY over the top. It trumpets and is just annoyingly loud. I just recently purchased the Flowmaster American Thunder and will have them on the car in the morning. I will try to post a video. You can look at all the videos online you want, but it just isn't the same as hearing it in person. Roush is the way to go if you are just looking for a quality cat-back system. The sound is amazing!

I got the Roush! Installed them over the weekend, was an easy install. Just so much more louder and vicious. I almost went with the Flowmasters but everyone has them and plus, I don't think the engine sounds right with the new 5.0 and old-school sounding Flows.

The Roush's give it that Mustang sound, but with a strong European accent that I like.

I ordered the roush axle back set last week from AM and received them Thursday.
Installed on Saturday, WHAT A CHANGE! These sounds awesome.
My only issue is, here in Santa Barbara CA there's not too many 2011+ GT's around. Theres an abundance of V6's but not many GT's here. My 5.0 is red with white racing stripes so I already stick out, now it's just overkill. I'm worried about getting too much attention.
Wonderful looking though, cant get too much better looking.
