Hey guys....just wanted to know if there was any significant sound difference between the mac long tube headers vs the bbk long tubes....are they about the same as far as sound goes???...i know bbk is better quality but i was concerned with that sound that the long tubes produce...i had mac on a 5.0 but thats another story...i heard the bbk long tubes on a 4.6 and they sound really good but i wanted to know if macs product sounded about the same, of course both with h pipe and chambered mufflers jus different long tube brands......any help would be HIGHLY appreciated and thanks in advance!
