I am buying an exhaust brake for my truck. I have read every previous thread and can't decide between Jacobs and PAC STYLE. I have two friends who have the Jacobs and love it. I found an exhaust brake made by US GEAR for my truck which gets installed on the bottom of the truck not by the 1300 degree turbo and is operated electrically. It is also $650. 00. This looks like a dream to me. Has anyone used this brake before or if you know of any downfalls about this type of exhaust brake please let me know. TY
