Hearder Install? I just ordered QTP lts and catted Y and was looking for some advice on the install when they get here. I know it won't be as easy wrenching on my old GTO. Any info on helping it go smoothly would be great!!
Everything that I would tell you is in this thread https://ls1tech.com/forums/showthread.php?t=139142.
Easy install. Need to jack up the car pretty high. I used SUV jack stands. Take out plugs first. Rear passenger plug comes out from under the car. Old y pipe was a pain to wiggle off. New y was also a pain to install. I removed the vehicle cross brace and left it off. Retighten header bolts if needed after driving. Ticking indicates a header leak. Put antiseize(sp) on header bolts. Do yourself a favor and install poly engine mounts while the headers are off. Grind down the engine casting that is found at the bottom of the passenger side of the block.
