what size is the exhaust at end of the header?
also i saw a high flow cat that said "not recomended for obdII" ... whats with that?
the downpipe is necked down to 2" i believe... can be expanded up to 2.25/2.5 without issue...
and a non-obdII compliant cat will throw cat efficency codes w/o some PCM reprogramming.
