Not an ITR, but 2.5 in should be more than enough unless you have fully built motor.

They make a full 3 inch? That would be awesome for turbo application

Chalk one up for full 3" exhaust here. Works just fine on my stock motor and can support just about anything I throw at it.

63mm or 2.5" will be fine. 80mm or 3" is good if your HP goals are high, say like 260+ whp or the like. It's also much louder too, so take that into consideration.
