Duramax diesel exhaust brake

Can anyone tell me of any problems or concerns in getting an exhaust brake put onto a 2006 Silverado HD Duramax? I've heard it might affect your warranty but I was wondering if someone out there has one and if they have had any problems. I know the the new HD Dodges have them but who wants to buy a Dodge? Please let me know thanks.......:cool:
