The RS II is a good choice. The chrome is bullet proof, and the metal is thick enough to last for years.
For a daily driver it will be money well spent.
It's more of a 7500-8k pipe so You don't have to hang on the throttle to make power. Match it up w/ some 5-6 gram rollers, yellow Stage 6 fly springs w/ two brass weights in the shoes, and a Malossi purple contra spring, and it will rip
That's a little different than the CVT set up for the Trek pipe.
