    I want a louder exhaust for my m1008. Its dual 2.25" or something odd like that. I want something loud but I dont really want it sounding like a gaser. Are there any loud mufflers that keep the diesel sound?

    The diesel sound is the clatter which you could drown if you put loud exhaust, unless you have a turbo then a big short muffler can unleach the whining of the turbo. :D

    I need mufflers for the '83 I just picked up. I'm thinking of some 2.5" Flows...probably the 50 series. Glass packs will eventually clog up with soot.

    Thats a neat thread, my buddy has run a number of 6.2Ls, and they never really struck me as diesels with a strong exhaust note like a gasser... He had one straight piped, and at the time I would have said it sounded like a muffled small block. Maybe I will try a set of those 30 dollar cherry bomb mufflers from Crappy Tire (think pepboys on crack), they had an awesome exhaust note on my old 350 :)

    I'd think anything that helps scavenging will help the motor make a bit more power...

    Yeah, it always help when you put the crossover pipe to help equalize the pressure when those 2 cylinders on one side fire consecutively, leaves more room for the gasses to go once they get there, that is why it's better to go back as far as possible to the manifolds.
    :D
