I always used to drive my GM 6.6L-LLY on hilly areas and I need an exhaust brake now. I have chosen BD exhaust brake http://www.bcdiesel.ca/en/bd-remote-...ry-exhaust-2-2. But I have still concerns about installing the exhaust brake. What is your view on having exhaust brake in the truck? Do you have any other brakes to suggest me. Please answer me as soon as possible.
