Hey fellas. I wanted to ask a question. I own a 2006 GMC Yukon Denali and I'm looking to replace the stock catalytic converters. Are there any differences in the cats for 5.3 and 6.0 liter engines? I might be going to the scrapyard to pick up a pair of semi good ones. I'm not sure if the fit or if it will affect anything in particular. What do I look out for if there is a difference. Is it ok to just pick up a pair regardless of 5.3 or 6.0 engine?

They should all be the same if I’m not mistaken.
Mine are clogged up too I had planned to either “gut” or remove them all together when I put the Longtubes on
