ZX9R exhaust on a ZXR750?!?

Considering that a B model ZX9R engine fits into a ZXR750 frame, would/does the ZX9R exhaust fit onto the 750 motor/bike?

Have spotted a ZX9R exhaust system on eBay but not sure if it'll fit!

It's a track bike, if that helps!

Cheers

Yep, the 9 system will bolt straight on but if it's a 4 into 1 you will lose approx. 10mm of ground clearance due to the 9 motor being 10mm taller, or if you're running a fully enclosed bellypan you might find the bottom of the pipes touches the inside of the 'pan.
If it's an aftermarket system you're looking at, most of them are 4-2-1 type so clearance will not be an issue.
ZX7R systems will also go straight on.

Zx7r system? Is it the same fitment?

Will start looking on eBay or the sales section on here for a system then!

Thanks

Zx7r system? Is it the same fitment?

Yep, the Muzzy headers on my ZXR 7/9 Streetfighter came off my roadgoing ZX7 & the Akra headers on my 750 Racebike used to live on a ZX9 B, all the aftermarket systems I've seen are 9 depth so they fit the 750 & 900 engines.

Sweet; Spotted a full ZX9R B system on eBay from Delkevic; they any good?

In a word, no.
A mate of mine bought one & it's a copy of the original headers, except that the std set has a divider in the collector to mimic a 4-2-1 system, the Delkevic is a basic old fashioned 4 into 1 type & the I.D. of the primaries is the same as the original set so there's no performance gain.
If I were you I'd hang out for a s/hand name brand set to come up on the 'Bay, just use the stockers until then.

Would a system from a ZX7R fit? Spotted an Akrapovic titanium race system in the UK for $1000 brand new and delivered!
