I have discussed this with another member recently. He just installed a set of "high flow" cats and loves the sound. He also says the truck performs better.
I am still investigating. A question has arisen. Maybe someone out here knows more. Stock cats are OBD and 400 cells per sq in. Aftermarket performance cats are the same. I was told, point blank by a muffler shop and performance shop, that H2's have "high-flow cats" as a stock item. And new ones would do no good unless there was a problem with the stock items.
Any assistance in this matter would be appreciated.
