Can I use a regular pipe cutter to cut my carbon bar?

I've been told not to use a pipe cutter but haven't tested the advice. Any 32 TPI saw will work or you can get a special carbon blade from Park Tool. IMO, they both work equally as well and can be had for $35.

Only if you want to destroy it.

Buy a carbon fiber saw blade or take it to a shop that has one.

Ive never cut carbon, but I believe you neeed special cutting tools when
laying up carbon, its a carbon filament after all. Pipe cutters are just like
a pizza cutter, fine for soft metals such as copper, aluminium etc

I would imagine a pipe cutter would just compress the carbon, causing fractures
and delaminating the layers, cracking the epoxy, just a mush mess, everything
but a clean cut, not what you want.

I've cut a handful of OneUp carbon bars with a regular $3 hacksaw blade - and a guide. No prob.

Sure, you can get away with it if you're super careful. If you're not, the teeth will rip off/delaminate layers of carbon. I wouldn't expect a person who thinks to use a pipe cutter to understand the structure of the composite well enough and be careful enough to succeed.

No pipe cutter for sure. Hacksaw and 2 old grip clamps as guides should work.

I lightly use a pipe cutter to score it around evenly , then cut with a hacksaw using the scored line as my guide.

Then a quick hit with a belt sander to clean it up
