hi guys,
I think i have a cat going bad on my 2001 astro. I have a bad smell after getting on it heavy. Do i need to replace it with oem or can I go with a aftermarket high flow unit? I called my local shop and was given a quote of 200.00 each ( it has a small in front of a large).I can buy the whole thing from the maifold to the muffler for 280.00.Any help would be appreciated.
Thanks,
Bryan

This won't send a code ? I was told by a muffler shop that it wouldn't pass emissions.

the only thing in the exhaust system that would cause a code would be the o2 sensors . as far as passing inspection , even if your in a state that has the sniff test i highly doubt a bigger cat would make you fail . now a bad or clogged cat would defenatly make you fail emmisions testing.

Can I eliminate both the small and the large cat for the free flow one cat?
