Just an update; the car is still stock, driving around home returns mileage in the low-mid forties... Still deciding on what mods to do... The front O2 going bad, coupled with an exhaust rattle suggests maybe use the header from my Redline(install new upstream O2), make a cat less downpipe and see how much that helps... Every post about someone doing a header/downpipe that I've read indicates a modest gain...
