    Default EP3 - CAT to B-pipe connection

    Would anyone with experience of this be able to confirm the Internal diameter of the OEM connection between the CAT and B-pipe on an EP3.
    I'm looking to replace the flange and gasket on my OEM CAT where it mates with the B-pipe.
    I'm not sure if its 2", 2.25" or 2.5"

    Thanks
    Rich

    Looking about I think the gasket that is used between the CAT and B-pipe connection is this: (I could be wrong)
    HENDY - (18393-SH3-S00) GASKET, PRE-CHAMBER (52.5MM-53.5MM) 18393SH3S00 x 1 off

    which suggests its approx 2"

    I believe its part 17 in this diagram:



    So which is it 2" or 2.25" ?

    I believe no 17 is the ring that goes between the b pipe and cat, it’s not the gasket. Best thing to do is call / email tegiwa they will tell you straight away and will have one in stock at a good price. Cheers
