Hey guys, look at this soundcheck of a honda cbr 400rr with the scorpion exhaust!
It sounds amazing!

Does anyone know if a CB400sf (NC31) exhaust will fit an NC23? Im seeing some systems that are listed to fit both..

I can't help with this but if you are after an exhaust I have a moriwaki one I'd sell

I picked up this NC31 exhaust for just over 10k yen yesterday so I will give it a try and post back in this thread if it fits. It seems the NC31 pipes are easier to find.. especially the titanium ones

If it doesn't fit I may take you up on that moriwaki.. although a titanium system would be nice..

From looking at that briny think it would fit, the header section looks completely different to a cbr400 exhaust

In what way does it look different to you? Keep in mind the pipes are just loosely sitting in the collector and not sitting straight at all so its hard to tell. I was thinking the header pipes might look a little longer.. Im not going to know until it gets here and its a bit of a gamble for sure, so we'll see i guess

It looks the wrong angle coming down from where the headers are

The NC31 outer 2 exhaust ports are angled to clear the frame down tubes. It won't fit unfortunately

Sorry if this has already been covered but does anyone know what the exhaust can fitment is for an nc29? I have Graeme France race headers so can look at slip on's or 3 stud (with adapter). I have a two brothers exhaust on my CBR600F and like the sound of that so would go with one for the 400 if I knew what to get and if it would fit ok...

Well i've decided to go with an Aluminium end can from Graeme France which will go nicely with my GF race headers. I intend to make video of it when i get around to fitting so Ill put a link up on here when thats done. :grin:
