2003 2500hd lb7

I have a 2003 lb7 and would like to put a 5" down pipe back exhaust, full straight pipe. Has anyone ever thrown any codes that I should know about with this year of duramax? Just would like to know if I will throw any if I decide to straight pipe my truck, Thanks to anyone who replies.
