This is a reusable used genuine original Yamaha XJR1300 4PU-5 Exhaust Collector Box in excellent solid clean condition. This came off a 2001 SP model But may fit other models but please check before you buy. This has been stored for a good few years and I have brushed off the dust and was amazed at its great condition for 20yrs old and have lightly wire brushed it and spayed it to protect it. The original gaskets look good and re usable. Any questions message me, please see all photos as they also form part of the item description. Uk postage only or collection in person from WS6 area, Great Wyrley
