who makes the best ones, and how much HP gains can one expect?
Kooks makes the very best headers no doubt, but you pay the price for them. I am assuming you have the 6l80e, but do you have a 2wd or 4?
Good luck finding any headers that don't cost 1600$ that fit nicely around that trans.
how much hp would i gain?
15ish with tune.
Maybe 20.
crank hp or rwhp?
