This may well have been discussed before, but does anyone know for sure if the exhaust system from an NC23 or NC29 will fit an NC31? I've got a Super Four Version R, which has the Steel headers and bolt on can. I have just sanded and resprayed the headers but they will more than likely need replaced soon as the rust on them is pretty bad. There are little to no aftermarket options for the SuperFour when it comes to exhausts, let alone everything else, so I'm wondering if anyone has ever tried fitting an exhaust system from an NC23 or NC29 to the NC31. The Super Four has an NC23 engine, so surely the headers should fit into the engine block ok, but is it fitting around the frame that would cause issues? Let me know if anyone has tried this either successfully or not so successfully. Or if anyone has any other options then please let me know.

Thanks in advance.

Perhaps not in your backyard, but there are dozens of options available (new and used) from Japan:

i have an nc29 stock system in the garage you can come look at steve, maybe take some measurements to see if they look anywhere near one-another

cheers Rhory, will give you a shout when I get a chance and find out once and for all if these exhausts are interchangeable.
