Im not sure but its one of the two sizes you mentioned.
If you can pick one up for less than $100, I would say go for it. I got mine for free
Exhaust tips will only make your pee-shooter like slightly larger with no performance gain (its not like the wrx CBE is going to give you a lot of performance either lol). I believe the wrx CBE will help you gain the subaru rumble, if that is what you actually want?
