Alright, this is probably a stupid question, but I totally need an answer ASAP. I'm off to Hawaii on exercise (rough life the air force) and when I come back I'd like to have some e-cutouts waiting. I don't know the stock size of the exhaust tube so I don't know what size cutout to buy. Any help (and it shouldn't be hard for most ppl on here) would be greatly appreciated.

 

any muffler shop will make a 3" fit just fine.
