OK I want to replace the catalytic converter and the 3 bolt flange on the muffler side. I found the part I exactly need but I cannot get a straight answer what size I need for the inlet and outlet. If anyone can link me that flange extension or anyone that makes them. I don't need that catalytic converter please don't link me a cat/flange with it welded on. All I need is the 3 bolt flange extension that will bolt into the downpipe with about 3-4 inches of pipe. Exactly what the photo looks like. This is for a 2001 Jeep Cherokee XJ thanks.

 

Even if no one can post a link anyone know the inlet/outlet of the 3 bolt flange for the catalytic converter / downpipe meet.

 

Why not just wait until Tuesday & go to your favorite muffler shop, they probably have a million of them.
