There are plenty that will run well.
The 2601 or 2604 will give a good balance of power and fuel economy.
The 2630 will give a bit more power and use more fuel.
I can't comment personally on the 2602, but many people think it is a great pipe as well, and I have heard nothing bad about it.
I bet the JP 2620 will work quite well on the engine also.
