I would go with the pipe. A good RLV A2, you will have more fun when the clutch locks at 10,000 rpm. The non-sense that a pipe will cause increased engine wear is not true at least in my experience.
The can mufflers have a couple of problems. First there is a baffle plate inside the can. Notorious for cracking. A cracked inner plate is a DQ. Two, They don’t help to scavenge the exhaust gasses. Because they don’t help to evacuate the gasses they have a tendency to load up with fuel making it difficult to start the next time your on the grid.
The expansion chamber(pipe) helps scavenge the exhaust gasses. Yes there is more maintenance. You will need a good clutch too. I prefer the L&T 3 disc 4 spring or 6 spring.
