Is not the stock manifold a mani-cat on your 09? If so (I don't 'think' they changed from 05-07), why would you run two cats? (or for that matter, if your running a header for performance why would you negate the benefits by sticking a cat on the end of it?)
But! We digress. The question was where could seige123 locate a bung for his A/F meter on his stock mani-cat. A header is tempting, but regardless of what catalytic converter you stick on the end of it, it won't pass emissions if they do a cold start sniff test. Which around here they would if they saw an aftermarket header (and they will), or just fail it as it's not OEM. But, things are diff in various parts of the country so its really a local issue.
