I recently received a works resonated test pipe with a O2 bung welded on, and it didn't come with a screw to plug up the bung. Is it alright for me to put it on as it is or should I plug it up?
Take the pipe to the hardware store and get the correct size one and a washer, dont forget the antiseize if you plan on running a wideband later on. this was a very dumb question though.....
