Heh, I can sense your excitement...
Great 3" cat back - check.
AP V2 with preloaded Stage 2 maps - check.
Extra heat shield and instructions for how to trim it to perfectly complement a bellmouth dp - check.
Having the ability to convert everything back to stock - check.
Now the only thing that remains is the bellmouth dp and a fresh turbo to dp gasket and some spare time for installation...
+26.0% HP and +31.0% TQ (give or take), here you come!
