Default 09+ WRX...TB to IC hose ?

I was hoping someone can tell me the diameter?

I have a leak coming from there (pretty common issue, apparently), and before I go out and buy an aftermarket hose, I want to take the boots off the ends of the stock hose and fasten it back on with some T-bolt clamps.

I did a search on here and got conflicting info. Can one of you confirm if I need 2.75" clamps, or 3" clamps?

Just buy a aftermarket hose, if you take the rubber caps off the oem hose will be too short. I believe I bought 3 inch t-bolt clamps

Measure the circumference then divide by (pie) and you have the diameter.

I just purchased and installed the avo ic-tb hose. I used 3.25" t-bolt clamps as per rallysportdirect. Perfect fit. Just gotta make sure you have an extra deep socket. Probably could've gotten away with 3" t-bolts but they're wouldn't have been much wiggle room. Definitely 3" for the stock hose.
