Cool, thanks for the info NAVY.
Mowton, don't tell me thats a before and after dynograph where the only change was the dynatech headers? You gained 37rwhp/39rwtq just from the addition of the headers??? That can't be right. Iceman only gained 9/17 (peak).

Want a quality set but don't want to overpay and Dynatech's are on sale so wanted to hopefully get some opinions from people who know.
Thanks,

I chose Stainless Works for my 02 Z06 and have been VERY happy. I have the complete exhaust system which is: 1 3/4 stainless LT headers, Random high Flow Cats, 3" X pipe mid section and 3" rear section with stainless works duel outlet mufflers.
I installed a VARARAM VB2, ported my own Throttle Body, 175 deg thermostat, smooth coupler, and a tune. Results are 02 Z06 with above mods- 375 RWHP and 365 TQ.
I just purchased heads and cam which will be giong in this winter!!

Quality, fit,and finish of these headers is EXCELLENT! They are super easy to install!!!!

Bill, looks good but for an 02 Z06 with LT's, exhaust, ported TB & intake 375rwhp is pretty low. Most 02+'s dyno around 360 bone stock. Not trying to be mean or rude, just being honest. Was that on a mustang dyno or something?
