The pipe on the left is bone stock,the one on the right looks like it has been cut shorter and ground down to except an after market muffler.Be aware that header length does have a bearing on tuning, the header length for our motor is between 30 and 34 inches as I recall and I believe Suzuki set the stock at 32 " but you'll need to check "cause my brain ain't what it use to be!.....checked ....I was incorrect the stock length of the header is 30" and should be no shorter than 27"

KRIS,WHEN THE EXHAUST VALVE OPENS PRESSURE WAVE MOVE DOWN THE EXHAUST HEADER UNTIL THEY REACH THE MUFFLER THEN REVERSE TO GO UP THE HEADER AND HELP DRAG THE LAST OF THE EXHAUST GASES FROM THE CYLINDER BEFORE THE VALVE CLOSES SO THE HEADER LENGTH IS IMPORTANT ,THAT "S WHY STRAIGHT PIPES PERFORM SO BADLY,THE WAVE DOESN'T FORM UNTIL THE END OF THE TAILPIPE AND ARRIVES MUCH TO LATE AT THE TOP OF THE HEADER.
