THIS MUFFLER CAN BE USED TO REPLACE MUFFLERS WITH 1-1/8 PIPE.  TO DO SO, SOME SIMPLY CLAMP DOWN THE MUFFLER CLAMPS TIGHTER OR PUT SMALL TIN SPACERS IN.  OTHER OPTIONS ARE TO WELD PIPES INTO THE MUFFLER OR PUT THE MORE COMMON BIGGER PIPES ON.  AGAIN, MOST SIMPLY CHOOSE TO CLAMP DOWN THE MUFFLER CLAMPS TIGHTER. BUT WE SUGGEST ORDERING THE CORRECT MUFFLER  C26974 
 
PLEASE LOOK OVER PICTURES, MAKE SURE THIS IS THE CORRECT MUFFLER THAT YOU NEED.  THIS MUFFLER FITS MOST ONAN POWERED 200 AND 400 SERIES TRACTORS WITH THE  NARROW HOOD AND A FEW YEARS WITH THE WIDER BULGE HOOD. INLET PLACEMENT IS THE WAY TO TELL IF THIS IS THE RIGHT MUFFLER FOR YOU OR NOT.  THE INLETS  FOR THIS MUFFLER ONE COMES IN ON THE SAME END AS THE EXHAUST OUTLET AND THE OTHER INLET COMES IN AT 90 DEGREES AT THE OPPOSITE END ON THE 'SIDE' OF MUFFLER.
