I know the exhaust is 2.5", but is it ID or OD? I'm gonna remove the stock muffler and resonator on my '12 and put a 14" Magnaflow can on there but I wanna get butt clamps from the same place and need to know before I buy. Does it even matter?

Measurements are usually inside diameter, but shouldn't matter. The wall thickness is maybe 1/16-1/8 tops.
