    Your best bet is to replace with a d plate if cat is more than likely gotten hot and the honeycomb inside will clog or suck completely through. A cat is 700.00 a d plate 150.00 approximately. But may I suggest only 91 octane fuel and only use yamalube. I also add 1 ounce of oil per gal of gas straight into fuel. Reason being I don't trust the oil injector to always be spot on. Good luck and I hope this helps.

    Get rid of the cat. I blew a motor because of that pos. The element broke free and lodged itself sideways, clogging the exhaust.
