Hey all, I have a 2006 Accord coupe V6 with the 6 speed manual. Im thinking of making a test pipe to delete the third cat. I was thinking id just find some spare flanges, weld them to a pipe, so i can just pull the old cat and install the test pipe in one blow.

Problem is I don't know which flanges to get nor where to get them. 2nd part is im not 100% sure what diameter of pipe i have... I've seen mixed answers.

Any help would be great. Thanks!
