I just received my mac off road h-pipe. Didn't come in durablack like I ordered but I cant wait another 3 weeks so whatever, I'm installing it as is. First question is=do I use the same hardware on the factory stock exhaust manifolds for this h-pipe, because it came with new hardware=but I can only imagine how hard it would be to take the old rusted studs out of the stock headers! Second question=any tips on making it easier to take off and re-install the smog pump air tube to and from the h-pipes. Thanks for any help. Heard of using a hose to reinstall the h-pipe to the air tube, anyone know where to get this hose?
