Yosh Exhaust Jetting

Hey everyone, the search is down and I am looking to poll the experts for some info. I have an 06 WR 450 with all the mods done, a PMB exhaust tip, jetted at 168 main, 48 pilot, 4th clip needle and a boysen a/p cover. The bike is dialed and I have a Yoshimura TRC full system on the way. I'm curious what kind of jetting changes to expect.? I'm running mostly sea level elevation. Seems like opening it up with that exhaust will need to fatten up the main but I'm not sure how much and whether or not to change the pilot cicuit too. I'm very good about 1 change at a time and being patient, just looking for some suggestions of jet combo's to take with me for a tuning trip.
