Dan,
Check the Moss catalogue for exhaust down-pipe for a '75 B. The
'75s and, I believe '76s did not come with cats. Make sure the rest of
your exhaust is compatible with the '75 down-pipe (check part numbers).
If your not sure about the compatibility, ask Kelvin.
Recommend, if you're so inclined, that you install the twin HS4
setup with separate intake & exhaust manifolds. I did this on my old
'78 and there was a substantial low RPM power increase. Not much
increase at high RPMs which, I believe, is due to the single carb cam
(if I'm wrong about the cam, please correct).
Good Luck, Skip '74 B

Anyone replace their cat con with a piece of pipe on their '75 and newer
B? I want to dump mine - don't need it here with historic registration -
and am wondering what others have done. I guess I could simply hollow it
out but I'm not sure if there is anything hazardous inside that I need
be careful with..... I recall seeing 'test pipes' on eBay from time to
time. I guess I could also go to a local muffler shop with the cat and
they could make up something...
