Quick question for the newbie that I am.... Does anyone know if just shimming the needles will be ok for performance when doing a Yoshimura slip on or full exhaust? Or do I have to do a complete re-jet?

Any help is always appreciated---

From what I know, you don't have to do anything with a slip on exhaust of any kind. Its just that once you go with full exhaust, then jetkits are required.
