I am trying to find out if there is an exhaust brake made for our 2004.5 automatic. It was build in February 2004 and is the 325 version engine...

i use the pacbrake also. its the best bang for your buck. plus it adds onboard air to your truck with is a ++PLUS++. good for my air shocks, any air tools needed and the most important, my train horns.

one thing that happened to me after my pacbrake, i have blown seams so far in my stock exhaust. i would be looking into a exhaust replacement also if this happens to you. Its not worth fixing the stock exhaust if you cannot weld yourself.
