Hi, I have a 2006 2500 and would like to add an exhaust brake. For those who have installed one, do you have a link of where to buy? Is this a DIY install? I've done a lot of work but time permits only basic jobs of around 4 hours and I try to avoid big tear downs. On the install, I hear that the 2006 "supports" the exhaust brake. Does this mean you don't have to drill any holes?

Thanks for your assistance.

Matt
