Hope this helps, Dennis

Thanks Dennis. Lee, the driver's side has a ball flange but the passenger side exhaust pipe just has the triangular flange. I can see on the flange where a gasket has been. It looks like a I need a sleeve with a flange welded to it to go onto the CAT. The sleeve would attach with a clamp.

Does anyone know if this is how the stock setup is?
