Just installed the 2010 GT500 mufflers on my 07 4.6L GT. Love them. I also have a cut and clamp X pipe that utilizes the stock cats. Nice and quiet inside the car, but has a great tone.

Tried to make an exhaust clip, found out the clutches in my rear end are worn out so it turned into more of a one-tire-fire video :(

I was wondering why it wasn't hooking even under half throttle.
