01 WR 426f jetting Change

Hello everyone, forgive me if this has been addressed a hundred times before but i can't find what i'm looking for in my searches. I have a nice 01 wr426 and got a ridiculous deal on a brand new old stock Pro circiut full exhaust for my bike. I'm @ 1,000 ft above sea level in northeastern ohio. Any suggestions on what jetting changes to expect for this. Thank you in advance.

no i did not. man, thank you so much.

No problem. I just stumbled on it recently myself, and it looked like there was some great info in there. I hope it helps you out.
