Xpipe VS Muffler off Collector
Do you mean sticking a muffler on the collector like that? i'd imagine it would give you the maximum flow up top, but you'd sound like a top fuel dragster when you were in the drive through at mcdonalds

EDIT: i missed the part about the x-pipe you already have. IMO i'd just install the x-pipe and put the mufflers on the end before the axle, seems to be the norm for performance.
