Running in new DRZ with T4 exhaust

I am waiting on the delivery of my 05 DRZ 400 (Im in Australia) and have already bought a full pro-circuit T4 system for it and was wondering if i can put it straight onto the bike or should I wait and run it in first? I will eventually do the airbox mods so will also be changing the jetting but will the bike still run ok with the pipe on it and the standard jetting? I just dont want to go destroying the engine straight away.

Thanks Guys.

I would say NO.I don't know how lean the bikes come jetted down under,but installing a freer flowing exhaust would make it run even leaner.I did just what your proposing on a new 2003 XR650L and it ran very poorly and very hot.
