Original factory exhaust system removed from a 1990 Kawasaki Zephyr 550 (ZR550-B). This is the complete stock setup, including the headers and the muffler. Condition Details: Overall, the system is solid and "looks good" once mounted. There is surface rust on the header pipes (typical for these bikes), but the metal feels thick and there are no visible rust-through holes or soft spots. Muffler: The chrome on the canister/muffler still has a good shine but may have minor pitting or small scuffs from normal road use. Fitment: OEM for 1990–1993 Kawasaki ZR550 Zephyr. Performance: Perfect for getting that quiet, smooth factory sound back or passing inspection if you currently have a loud aftermarket pipe
