Maybe he had good luck with the T/B, but most of MAC's products aren't worth it. The only MAC item that I would buy is thier cat-back, which sounds nasty. Thier throttle-bodies stick(read the parts reviews on Stangnet if you don't believe me), thier headers arent worth it because they have single flanges(warp really bad, MAC long tubes usually don't fit right) thier girdles crack, and the C/A intakes don't add much HP. The only good products from them I've dealt w/ are the shifter and catback. Stay away from the T/B and get an accufab, holley, or BBK
