Default hp from Headers and Y-pipe? air induction?

I just bought a 2000 Z28, and I ordered a pair of Hooker Headers and a off-road Y-pipe.(minus the cats) How much HP will I gain? The rest of the car is still stock for the time being...

I think 20-25 hp (guess) I do know you will get the most hp after you get a tune. I just put headers on my 98 and you can tell it picked up hp......but to get the max out of this change you will want to get a tune.

the lids are pretty much all the same. get the one that you like-lookswise-the best.

and headers after the tune could give you anywhere from 30-45hp. those are numbers ive seen. but dont just expect the 45.

my buddy gained a little more than 30 after the dyno tune, and that was through a 3200 vig.

and the only things that went on that day were the stall and the exhaust.
