Mr Hide:
No experience with Doug's package for the Z06, but am familiar with his background, and he knows how to make horsepower in a Vet, PLUS handle well! There are a large number of aftermarket suppliers/manufacturers out there, but Rippie has the experience and skill to do it right!
Good luck on your Z....I'm sure others will have the answer to your specific question.
