I love my pacesetters! And yes use the stock manifold gaskets and I used the stock manifold bolts as well. They were a better quality bolt then the ones that came with the headers. As far as gains my truck seemed to feel like it picked up more from the headers/or-y/catback then it did going from the 3.42 gears to the 4.10's.

 

It's okay lol... I have state farm probably do them a favor and they can upgrade to a 6.2 fully loaded (Javzh)

 

Lmao I hear that. Damn going to gears made a huge difference so damn, might have to do it

 

did someone say 12pack?

 

Just did mine last week end. From summit. Left bank header goes in from top (tight fight) rt comes up from under. Yeah also got those crapgaskets No ext's tho. But didn't need um Do yourself a favor take the mud panels off And be prepared to take off crossmember if u wish to save your oem y
"CAREFUL removing O2's that u will reuse. They will be tight n u might strip threads like I did "bastards" let em soak n pb blaster
Godspeed!!!

 

Thanks guys, might need a 12 pack after all. Maybe they won't be installed before the socal meet cause Justin is out of town, but definitely before my cam swap!
