I was thinking of installing an exhaust brake on my f-350 6.0 liter powerstroke and I really do not know a lot about it and I wanted some information. Do the brakes wear out the engine? Does it affect the warranty? Is the difference it makes worth the extra money? I will check with ford and their warranty department for the particulars and with my mechanic but I just wanted some real-world opinions on it. The manufacturers, of course, only list the benefits of such a system. Any replies or opinions would be greatly appreciated. Thanks.
