Upcoming Header Swap question...
Right now I'm running Mac Mid headers with Catted Y-pipe, but i'll be swapping them out in a few weeks to Pacesetter longtubes and off road Y.
With the Macs my current best timeslip is 12.81@110. Anybody have any idea how much difference it will make in my trap speed going with longtubes and no cats instead? I want opinions whether it'll make a difference, because i don't want to be disappointed if i trap the same mph. Thanks

I just switced from mac mids, ORY, and borla to Pacesetter LT's and tsp duals. I definetly noticed a difference. But i dont know if it came from the headers, duals, or a combination of both.
