Exhaust parts - looking for drawings

Hi, I was wondering if anyone here could point me to a source of dimension drawings or a maybe a 3D scan in e.g. step or stl of especially the rear downpipes and collector box for RC24 II (J and K models from 1988/89).

 

No

However this may be of use https://www.ebay.co.uk/itm/14512166...p8TDMzmL39j744fvy5EliXAg==|tkp:Bk9SR6TV5t6UYg

 

Looking to make your own?

 

Hi Rouge - Yes, thats what I am looking into. Especially the collector box on the FJ/FK. I had the luck to find reasonably good downpipes with a some years left and these are the more complicated. I imagine that making a new collector box wouldn't be too complicated - provided you know the dimensions
