    The mufflers on our 84 W900B are getting worn out and getting a couple small holes in them so its time to either replace or upgrade. Anybody have any idea how much it would cost to go back stock vs putting straights on it? It has a 350 Big Cam Cummins, and I've been toying with the idea of going to 6-7" straights, but not sure its worth it. And I haven't ever had to buy a new exhaust system, so who besides Kenworth is a good place to buy from, whether its stock or straights?

    Just need mufflers? Get a pair of straight thru mufflers online. Should be less than 400 for a pair.

    @Bakerman what brand where they? It's just a farm truck so not looking for show quality or anything.

    Just remember those old cummins can be LOUD with straight pipes. Especially on the jake. I know you said its a farm truck but it can get annoying.
