well i picked up a free set of pacesetter long tube headers and have quite a deal on install, so being the cheap butt like i am im tryin to save some cash. would it be cheaper to have him fab me up a y pipe and maybe some dumps or should i just buy the pacesetter y pipe and run it in with my stock exhaust? i know i need some good gaskets and lockings bolts. any other tips/info ill need before i get ready to have them put on?
