02 WR426 question on Pro Circuit T4 exhaust

I have looked in the jetting info section and did not see anything relating to my set up. I have on 02WR426 with a pro circuit t4 slip on and head pipe. I am wondering if anyone has this set up and what kind of jetting changes did they have to make. I live in Illinois and we are 790 ft above sea level if that helps.

Thanks for any help
