Ok, Im pretty set on the Flowmaster Am Thund. 40 series catback. Now for the rest... I have 3 midpipes in mind... I need cats on the midpipe, I was thinking either the MAC shorty H... if i get that im gonna get the MAC long tubes... the BBK X or H shorty or OEM length with ????? Headers.... Bassani OEM length X with ?????? Headers??? Basically, what do you reccommend for a Midpipe with Cats and Headers combo... all feedback will be helpful... thanks!
