    P/N 544-2503 is a disc only assembly with an adaptor, 360 degree exhaust shield, 12 discs, closed end-cap and disc screws & nuts. The adaptor (mild steel) is designed to be butt-welded on the end of a 2.5" pipe and receives the shield, discs, end cap & hardware. The amount of discs can vary to individual need. The overall OD (exhaust shield) 6.0", the adaptor is 1" and so is a stack of 12 discs.

    The 4:1 system for the '73-76 KZ900 is still in production and is offered in black (127-61001) or chrome (128-61001). Part numbers and prices vary with finish and baffle choice.
