shorty header + test pipe = benefical?
i know hp makes a full race header consisting of the shorty header combined with the downpipe, but is it pretty much the same going the megan racing test pipe/resontaor and some shorty header route? any differences?
what are advantages/disadvantages?
and the MR test pipe = 2.5" ? or was it 2.25"
