keep MACs or go with LT's?
my friend gave me a set of flowtechs with ceramic coating and i have them here, they have the emissions fittings and whatnot, but they are brand new
i was wondering if it would be worth it to switch to longtubes from what i have now...i'd probably go with kooks or QTP...
i have AFR 205's /G5X3 112 and all that BS to go in as well...what would be best for my car?
