ah, okay... keep those cats in! They really do not hold anything back and if your in an emissions nazi state then you'll need all 5! Im assuming you want duals out the rear? What muffler are you looking into and are you loking for straight out the back duals or 45 degree swept duals at the rear bumper corners?
thats what i thought, im thinking a Flowmaster super44, single inlet dual outlet, with the pipes coming straight out the back? i think? or on an angle, not sure yet, but yeah duals
you guys should be right i was thinkin 2.5 inch also. and the flowmasters a good idea ( right guys lol). now as far as the cats go yes they do hold alot back but if you need to smog it to tag it leave them on lol.
FLOWMASTER SUPER 44!!!!! Hells yeah!!! Great choice of muffler! If i were to do duals out the back on mine it would be straight out but im a lightning side exhaust kind of guy on all my ford performance vehicles so thats just what I would do.
I just love the side exhaust like that! If I ever get another ford truck or a mustang or anything made for going fast... it shall have the side exhaust lightning style as long as it looks right.
