Question on my 2000 z71 Performance.

[dougs01gt]

What is the biggest power restriction in these trucks. Exhaust, intake???

[Butch 02 Denali]

The factory tuning and torque management, no question about it!

Ditto, ENGINE TUNING!!! I have a Dynomax exhaust, but I doubt it bought me any power (sounds great, that's why I have it!). I want a K&N Series 77 but really just for the look. Someday I'll convince my wife to let me order the Westers and really play some!
