do you have a haynes manual? it lays it all out. the torque for the bolts is 25 ft-lbs. start at the two center ones and work your way out when torquing. you also have to do a heat cycle when torquing them. do the original torque like i just said, start it up with everything torqued, let it completely warm up, then shut it down, and torque them again. Don't use anti-seize compound on the header bolts, or they will never hold torque. i would just make sure that the threads on the bolts are clean. the only ones i would use anti-seize on would be the y-pipe connection bolts. when you go to take the headers off, i would suggest doing them while they are still a little warm. heat does help. and soak them in pb blaster. chances are, you're probably going to break a couple or not be able to get a the ones off the y-pipe. if that comes, stay patient and work on it. you might have to drill and extract or cut. just know that it's going to take time and patience.

 

how was the performance and was there a change in exhaust note ??? thanks homie

 

there is a bit of a difference in performance(for the better). the exhaust note does sound a little deeper, but i dont have a good enough exhaust system behind it to REALLY tell if it has made a big difference or not. next step after this is dual pipes out the back. we'll see how it turns out. and i'll keep you updated. quite honestly, headers for 150, can't really beat that. and the warranty is from pacesetter. weird huh? summit shorty headers with pacesetter warranty. only bad thing was it being painted. i would have rather it be not painted. it just flaked off after driving 20 miles anyway.

 

yeh,summit headers are made by pacesetter.i thought everyone knew that.

 

I agree with the painted thing I got the black painted shorty style Pacesetter headers and it did the same thing, although I did buy them for performance and not looks. PB blaster with the combination of a can of Rust off or something worked great on mine. I don't have alot of the clearance issues some of the members have due to the 3" body lift I have on top of the 6" Sky Jacker suspension lift. As a matter of fact most of my exhaust manifold bolts were removed through the fenderwell just above the dual shock tower. Finish your exhaust it'll sound great. I didn't go with duals straight back 1) I don't know where to run the driver side pipe ( inside frame outside frame ), and 2) I 've been reading mixed views on the drop in HP and low end torque due to the drop in back pressure. I run a stock cat with a single 3" exhaust pipe split off into (2) 2.5" tail pipes exiting at angles out back. In between this sits a 3" single center in/out Flowmaster Super 40 muffler and I get great performance and no loss of low end torque.
