Will a B model exhaust fit an H model?

Is there any difference in the frame that will cause clearance issues? It isn't easy to find an affordable exhaust that specifically states it will fit. Thanks!

Need to know the specific models. the letters alone are pretty much meaningless as there were several different sized KZs of each.

I need or want to put a Vance and hines 4 into 1 exhaust on a 81 kz650&;csr. But all I find are exhaust for 77 thru 80 kz650 b models. I know it'll bolt up to the engine and all, just concerned about any difference in the frame. I think it'll be ok but if anyone knows for sure. Let me know. Thanks. Don't wanna spend that kinda money unless it fits properly.

Probably any KZ650 KZ750 4-1 exhaust system fits just about any 650 or 750-4. You may have to fabricate a muffler bracket. If you can't find anything listed for the KZ650-CSR, try searching for KZ750 Ltd instead >> the 750H has the same frame & muffler system.
Also, I think Z1Enterprises sells Delkevic ss exhaust systems.

Kind of related, here's a 70s 650 with a stock ZR750 ss muffler system.


ZR7 or ZR7S w stock exhaust. same as pic above.


1981 KZ650-CSR w 1980 KZ750-E1 mufflers. direct fit. the 750E mufflers are 6" longer than the csr.
just showing that some 650 750 systems can be interchangeable. the E frame is similar to the csr.
