I sold my 99 dually and just got a 93 12v and planning to get an exhaust brake and stacks, anyone know the best set-up for a 12v? Looks to me like a special downpipe will have to go with the brake or use the in-line type. Got most of the pipe for the stacks except for a few short 90s, also any recommendations on a brake, the price on the Pac-Brake looks the best? Thanks, WV Smoker
