I ran pro circuits on my first shee,
T'5 on my second shee and currently running CPI's
I have ridden many different pipes, if you are looking for a all around GREAT pipe, i wouldnt choose anything other than a set of pro circuits.
They are just insane, smoother and snappier than anything Ive tested.
My 2 buddies are currently running them, one has some nice port work and bolt ons, and the bike is insane, other has a clean up port and - 2 swinger and for the 20 mins it was running, it was nearly impossible to keep the front end down. They rev out really well and in my opinion will run with any pipe up top other than some drag pipes
I have not ridden a bike with rockets yet though, so i cant say much about them.
good luck
