Fitting a piper decat

  1. #1
    Does anyone know how these fit?

    I know how a normal decat pipe or cat fits and a standard exhaust with the cups and the bolts that sit inside it, but the piper does not have the recess for the cups to sit into, it is a solid piece of metal. Shall I just use a normal bolt? Do I need to use the springs?



    Thanks
