I got my Bassani BX50933 in the mail today and got a couple questions. I was under the impression that the tube from the air pump to the mid pipe goes before the converters. am I mistaken? and all pics I see for this product has huge converter casings. Not these small ones. For any one that has this x pipe, is this correct? this is only part of the exhaust. I have the pipe that connect this to the headers..not pictured
