NC21 has a low level exhaust



Collectorbox is different as is exhaust can.

NC24 has a high level exhaust



Collector boxes do fit both engines but are different, as far as im aware there is no link pipe to convert the nc21 to a high level system, what you can do is use an aftermarket nc24 link pipe and cut the collectorbox up, or cut the link pipe to bodge it.

Heres a lovely picture of RCV4's stainless steel copy.



Here is an image of the NC21 box.

Knew it had to be too good to be true, ah well Ive bought it now I'll have a think about it and see what I can do, the way I'm looking at it is that this bike will be classed as a classic from next year and with that mindset I'm not going to be expecting everything will be easy to get hold of etc. That stainless exhaust looks beautiful but a bit out of my price range right now tbh , thanks for the info anyway guys
