Re: Catalytic Converter Pinging?

Wow talk about reserecting the dead with this old thread.

The cats in the H2 are notorius for failing. Mine failed on my 03 around 56K miles.

However I thought the Cats on the H2 where high flow straight through units??? This is what I have heard.... Can anyone confirm this? If they are in fact hi-flow cats there really is no performance gained buy gutting the cats. Also I would assume this should set a check engine light due to the post cat 02 sensors?
