Carbon is quite heat resistant and making CF takes some significant heat. However, CF cloth before impregnated with resin is like fiberglass cloth. The resin and CF together make a tough part.

So while carbon fibers made into a part would take a lot of heat, the resin would not and therefore you could never use it as a high temperature component.

This link details some OEM for CF that claims some people have stuck it on mufflers with adhesive but not made exhaust using only CF: http://www.protechcomposite.com/serv...FQyfnAodjGnG6Q

Titanium is the same strength as steel at 60% of the weight I believe. It's also notoriously difficult to work with and has bad wear resistance.
