In what I was saying with the cats that I have they already have 3 bolt flanges welded on.
Hopefully this will explain.
I will take a picture of the cats that I have and post up and you will be able to see them.

OOO ok...Thanks for clarifying...I kinda thought those were flanges but wasn't sure if it was different with high flow cats or something...So basically they are flanged so they can be easily bolted in or taken out...You don't hafta take pics I understand what you're saying. Thanks.
