Re-Jetting for FMF full Exhaust system

Hey guys

I am looking at putting a FMF full exhaust system (Power Core 4 muffler and power bomb) on my 2005 RMZ 450. I live in South Carolina and was wondering if anyone knew if I need to get the bike re-jetted after putting the FMF system on.

Thanks for the Input!!!!

I ran the same exhaust on my 05 with stock jetting & no issues a few years ago@ around 750 - 900ft elevation.
