Jetting Tips for a 2006 YZ450F with new exhaust please

Are there any riders using an FMF exhaust system (with powerbomb header) on the east coast? I've never touched my jetting, the exhaust system just arrived so I'm wondering if I should use another set of jets for my starting point. I'm in the VA & NC area if that helps to nail some things down. Any tips?

I have an 06 with the following; 48 pilot (42 stock) part number4MX19948-06-00,170 main (165stock), with needle #5TA-14916-LR-00 (stock for 07 bike) Ran tons better
