I wouldn't recommend a CVEC Pipe. Over time, the internal regulator will become gummed up with all of the exhaust goop. Thus it will eventually get clogged. They are good only if you want to clean your pipe after every run.
I don't own the Picco .26, but with any engine, you should select your pipe based off of how you run. Are you looking for more low, mid, or top-end? Or a combination of all three? Once you decide that, then you should shop for a pipe.
