Have installed the exact exhaust system on my RMZ 08. Also installed a JD Jet kit and an adjustable fuel screw to inhance the exhaust mods.

The addition of an aftermarket exhaust will not require jetting changes. The changes in air temp or altitude will require leaner or richer settings. A hot day (80F +) requires a size or two smaller on the MJ and one clip position higher on the needle. An average cool day requires stock jetting & needle settings but as it gets colder than average, go richer on both to keep it running crisp.
