    [IMG] As for fitting, yes. The sulfur smell... probably not. That's the gas.

    yah it is the gas. I was reading the recall on toyotas website. To much gas mixture is going into the cat.

    I remember fighting toyota about the issue back and forth. They kept telling me it was my air filter or my a/c. Though i never use my a/c so thats impossible. :roll:

    actually there is a TSB on corollatoys for certain VINs.........mainly the early 03's where they're finally taking blame for the egg smell. They'll replace your cat and reflash the ECU covered under the 80k emissions warranty.
