well you have presented me with new options,
at the moment ive sorted the exhaust up to the cats, now im focusing on the intake, so i ordered the h-dev spacer and MREV 2 lower, hopefully getting the airbox mod too, just waiting to see if my garage are willing to to try and fit new headers and cam shafts, i know most people think engine removal is easier...its all about money!
i have spent 4k so far, but haven't scratched the surface
