ultimate solution: go to a muffler shop and have them weld in two cats into your mid pipe, 100 to 300 cell should do the trick, then install the bungs at the correct angles. never worry about smog, or lack of performance, no CEL and no problems with the boys in blue, unless you have your car reffed, and they see that you've moved your cats, which in CA is mostly illegal, but this works every time. your O2 sensors do their jobs, your car keeps itself in check, no stupid witchcraft simulators, and no fuel mixture problems. can be don for under 400, which is still way better than paying the 2000+ for a new big name exhaust system with cats. as a gift to yourself, before installing your ebay headers, go ahead and take a dremel to the inside to finish them out.
