I know it's a 3" collector, but is it 3" ID or OD? I'm working on fabbing up a track only set of Borla XR1s just off the collector and I want the nice band clamps to seal it all up. I just need to do my homework to get the ID/OD right. The Borla is 3" ID and I don't have the car tore down to check it myself.

Anyone got a set handy? TIA!

mine were 3" OD and the 3"ID pipe fit over the collectors for the true duals I had.
