I have the GT500 axle backs right now, and they sound great don't get me wrong, but the tone never changes, it just gets louder. I want the Borla S type exhaust but the thing holding me back from getting it is how far the tips stick out, I wish they could be flush with the car like the GT500's.
A lot of times you can slide the upstream joints in the system into eachother to make the tips flush with the car. I had mine to where they stuck out just a bit on my '11.
