Now that I have the FI cat-back, I need to re-dyno and have the tune tweaked a bit but I hope to see around 320rwhp which is about the most you will get with full bolt ons and a tune. In my opinion, it is the perfect amount of power for this car for a balance of power, control and balance.
My dream is the GTM stage 2 supercharger though lol.

Do you really believe that changing exhausts will increase your overall HP, by +11whp?
I am more inclined to believe that it will only net you a few extra ponies at the most.
*Do you have a dyno of the 309whp pull?*
