    Default 02 bung Q

    I have a 2009 Yamaha Grizzly 700 EFI and will be using a dyno-jet unit that self tunes via a 02 sensor. I am curious if I could buy a 136-4700 mudslinger slip on.. with an exhaust bung already welded into it?

    The MudSlinger, P/N 136-4700, is a slip-on application and uses the OEM stock headpipe, which is where the o2 bung should be located.
