Quick question for you guys. What size is the flange on the cat connecting to the Catback or b-pipe whatever it's called?

On the sc it was always a large 3" flange that would mate up perfectly to the Cxracing flanges I buy.

Is this the case for the is300 aswell?

I'm going to build a 3" exhaust for it so it's ready for my build. But I rather not undo it and find out if someone knows the answer.

Thanks again
