Hey guys old thread but everything is at my house i will be starting the fabing of the first set of GV headers next friday the 14th.

nice, can't wait to see this actually happen. one of these days I should do headers on my GV. I bet it would unleash a whole barn full of ponies

Well im just waiting on the two head flanges ill be getting on wed. Power will be pretty good im thinking 15-20whp easy. these stock manifold are 1.25 inside diameter and very restrictive.

yea, they are probalby the crappiest looking manifolds I have ever seen in my life. not to mention these things have 3 catalytic converters when they are stock, mine only has two now though. my secondary cat was a high flow of some sort, but even after removing that I thought I felt a bit more throttle response. not much though. I imagine those two stock ones right off the manifolds are choking the crap out of it though

Well biggest upgrade i noticed was the 2.5" Down pipe vs that 1.50-1.75 POS front pipe.

Well guys got all my parts today I will be posting some more pics tomorrow. These are one offs and so far i am at 800 in material. So making these i will have to see. So far i can get 30-32" primaries i will see what i can get tomorrow

sweet, finally getting this done. Keep us updated. $800 is allot of money for material.
