Hi.. just wondering about mufflers... the inlet outlets are in different spots some both on one side some on the other.. and some are in the middle, etc. I replaced my mufflers along time ago with glasspacks and want to replace them with some magnaflow mufflers... but am not sure about where the inlet outlet should be... looking at some used.. and not sure if they are right.. thinking of just dumping the exhaust after the mufflers... how would they hang.. because currently my mufflers are only hanging by the back hangers..
