Exhaust - Kawasaki Z1 900 KZ900 4 in 4 Replica

  • Sale
  • $ 1,225.00

These chrome pipes are only sold as a set and include removable baffles and muffler connector clamps. These pipes do not have any stamping along the top of the muffler, so they closely match the original unstamped 1972 / 1973 pipes fitted to Kawasaki Z1 motorcycles. All pipes are unpacked and carefully inspected before shipping - these pipes are ALL premium quality (unlike some being sold that are B grade pipes).  The muffler joining hoses and clamps are now included in this set, however the mounting hardware is not included and is sold separately.


*Carb Settings*

These mufflers are all single walled tubing, as is the original Z1900 mufflers.  Proper carb setting will keep the header pipes from discoloring.  We have all seen that blue hue on our header pipes, some like and some don't, but in any case this can be kept at bay with a proper fuel/air mix.  Many of the older bikes had the Kerker style 4 into 1 pipes. For 4 to 1 exhaust setting, the fuel mixture is set low so the exhaust temperature is very high and causes the discoloration.  For the stock 4 into 4 setup, the carb setup is more rich and have a lower exhaust temperature so the proper setting of the carburetor can stop the header pipes from changing color.
