OK.... I ordered the BD Variable Vane Exhaust Brake the other day! When I asked them if using their product would or could void my mfg warranty.. first they said no way would it affect the warranty in any way... I tried to do some more looking around with no luck..

I called them back and got a tech.. he told me the following--
"To be safe, I would have a "hypothetical" conversation with a service manager. From what I understand a dealer can flag your Vin# and a restriction is placed on the vehicles warranty and will follow it no-matter what dealership you go to; I just want you to know everything I do- but it sounds like they should be able to help you out if you are a good-customer for them."

I am not really sure I want to have that conversation with my service rep.?? any first hand knowledge out here ?

I installed a banks speedbrake on my 2009 chevy, about a year after I bought the truck. I was worried about the same thing as you, but decided to install the speedbrake anyway. I needed to take the truck in a couple times for warranty work, so the first time, I removed the speedbrake (a big job). The second time, I decided the hell with it, that I would take it in to Chevy and see what happened with the speedbrake installed. The problem was an AC issue...Chevy fixed my AC, and never said anything about my speedbrake. Though I never pointed the speedbrake out to the service manager or tech.

I think you need to be ready to void the warranty in any area that your EB affects, IF something was to break in those mechanical or electrical components. In other words, you might have to pony up and pay for any repairs caused by the EB, IF there are any. It is a chance you will have to take.
