I bought mine straight-piped after the pre-cats, and I had a cat installed for inspection. I don't know what the factory setup is, but it has 4 O2s.

Nice.
How will injectors with 226k+ miles not hinder mpgs? New ones will help simply because they arent clogged and old. Cool air intake will help some. And a free-er flowing exhaust will also help mpgs.
