    hey all,

    bought a exhaust system with Rush mufflers for my dresser. it has O2 sensor bungs that i don't need. any idea what thread size they are? i used pipe plugs that will not stay in even with lock tite or anything else. just trying to keep from taking the headers back off and welding the holes up.

    thanks for any info...............

    They are 18mm, you should be able to buy plugs from anyplace that sells pc3 as they dont use the oxygen sensors or you could install a bolt, worst case scenario install an old oxygen sensor or spark plug, just knock the porcelain off the top of the plug and paint it black. Todd

    Shops that sell and install racing exhausts for the little compact cars have plugs for these as well.

    Daytona Twin Tech sells them, contact them by phone.

    Any performance hot rod store should sell bungs and plugs.
