2011 GT Cat back Exhaust?
A quick question for you guys. I just ordered a new 2011 GT. One of the first things I want to do is add a cat back exhaust. It will be either a Borla or Dynomax. My question is, does anyone know what kind of performance gains I can expect in terms of horsepower and torque?
Thanks a bunch, N.P. |

I went with the Borla ATAK catback....sounds awesome, but a little too quiet at idle. Really screams when you get on it.

Next to nothing for hp. The only exhaust mod that gains any decent hp is longtube headers and removal of the cats.
