Had a good talk with a guy from AFE. I will be getting their full exhaust system in a 4", turbo back.

He gave me the name of a few tuners, too. But I will check that guy out you mentioned, Dennis
You'll be happy with Kory's tuning. PPEI does good work.

I am talking to Gorilla. Heard of these dudes?
I can't let Doc Bob have more power with his new '17

Karl, are you waiting for me?? Need to get your parts list ordered!

I went with the FlowPro stainless 4" complete exhaust. It was half the price of the AFE

Kory has gotten LML's on the CP4 with no lift pump over 500hp to the wheels... Just sayin' lol.

507hp is about where the CP4 tops out... Give or take manufacturing differences.
