Anyone running jhm cat pipes?

[derek.kritz]

My buddy just had a cat go out on him and he is going with these. They have a 300 cell metal cat but haven't found much info on throwing a cel from the o2 sensor. Anyone have any experience with these? What o2 spacers is everyone using to pass emissions?

When I was debating cats, I was going to go with non catted pipes and put some 200cel cats down below on the downpipes. Another member here is doing this on his car right now since he has gone through stock cats. That way you can change them or put in test pipes later on easily.
