The stock CB1100 has a pretty restricted intake and exhaust. I'm not sure opening up one end without doing the other end will be all that noticeable.
Case in point - simply adding a Staintune didn't seem to boost performance on my bike. If you add a K&N but keep the stock headers and muffler you might not add much either.
But a higher flow exhaust like the Staintune, combined with a TSR air funnel and a K&N really frees up air flow and adds noticable HP.
As ACK said, a PVC is needed once you start messing with the engine in a major way.
If you want more power, use less restrictive headers such as Motogear "cat free" pipes or a complete aftermarket exhaust system. That will take things to the next level. A PVC is absolutely essential at that point.
Forgot to mention that when it gets dry and dusty, I'll put my OEM filter back on. I don't trust the K&N to fully protect the engine in adverse riding conditions.
