04 Duramax 4-5 inch exuast

I was just wondering your opinions about running a 4-5 in exaust on the



04 LLY deisel. I had posted about K&N air fiters and got split responses. The guys that do what I do, a lot of them have their exaust replaced the day they buy their truck. they don't care about the warranty. they care about milaege and added power. What are your thoughts? Bob :)

My buddy had a 5" exhaust and "The Juice" put on his 01 Duramax, made a HUGE difference.

Thanks Man ! "The Juice" is that the brand name of what he used? I haven't done a whole lot of checking around yet so I have no idea what they call some of these exaust kits. Thanks again, Bob
