that was another thing that i was wondering...which cat is more important?numbnuts240 wrote:also, iirc the cat on the dp is the one that actually makes a difference, the one further back is hollow. i found my rear one to be hollow when i changed it out for a catco. the primary one is still there. i'd find out for sure if this is true before you delete the important cat and fail emissions.
headers?

Re: headers? (Seanzyyy)
even if you have a test pipe on an obd1 car, it won't throw a CEL light.
even if you have stock components you can still fail in emission.

The front is the necessary cat. The rear is a resonator if I recall.
