Does anyone have mac mids with the y-pipe with cats installed on their f-body? I would like to purchase a set of these headers for my car (in sig) but I want to add cats in the y-pipe. Has anyone done this? Would I have any clearance issues trying to add two cats on this y-pipe? Here is the product in question http://www.macperformance.com/store/...roduct_ID=1442
