ok , got me 2 magnaflows from the bone yard for $10.00 great price!! brand new, fresh kill . I think I read that people were using a exaust for a resonator? if not thats ok I'll just grab I high flow one, after installing this is it safe to put on a 5% pully on the super charger? the other question is I found a 93 SHO in there with the 140 speedo looks the same will it work? thanks TED
