I have only had my Z06 for a week and am ready for a few mods. I am looking at a Vararam, Headers an X-pipe keeping the stock cat back. What would be a realistic RWHP gain? I want to stick with bolt ons for now. Thanks!
You are looking at a 15-20 rwhp gain (depending on the headers), but the increase from the Vararam won't show up on the dyno. You WILL feel it when you are driving and sucking in that cold air. :thumb:
Here you go, your exact mods. Vararam and QTP headers on a stock Z06. Only problem was the motor was brand new (original toasted on the owner) so the numbers are likely a little low but he picked up 31 HP.
