Exhaust sizing question

Quick question here. Are catylatic converter and muffler pipes measured in inside or outside diameter? What I mean is the 2 inch long inlet and outlet exhaust pipes attatched to the converter, if it states "2.5 in. inlet outlet" on the muffler or cat listing details is this referring to the I.D. or O.D. of the pipe?? Also is normal exhaust pipe measured in O.D., I think it is but I am double checking. So if a cat is measured in I.D. and exhaust pipe measured in O.D. would this be the proper type clamp to use to attach them? http://store.summitracing.com/partde...5&autoview=sku

Thanks for the help,

one is ID inside diameter the other outside diameter so one slips inside the other u can use that clamp but i 'd just use a standard u clamp or have it welded together... if it says 2.5 in and out then u have to get the next size pipe to fit over those ends like 2 3/4"
