    Normally when you have a SI/DO muffler the dual outs are smaller than the single inlet...I had true duals with 2.5" flowmaster 40 series delta flow mufflers, went to PaceSetter LT's with 3" ORY and single 3" exhaust and it was SOOOOOOOO much better.

    That's more or less what i was thinking.

    If i go this route, it puts me needing a new muffler. I'm curious to try something other than flowmaster. Like I said before, I'm curious about magnaflow and spintech but don't have personal experience with either of them. both seem to have a decent reputation.
    being a mostly stock truck and planning to mostly keep it that way, I think that decision will boil down mostly to what i like better as far as the sound.

    so what are y'alls opinions as far as sound? I know others have told me before that spintech is loud. I like it loud, I just want it sound clean and good.

    Like I said above. I went from dual flows to a single flow. Sounded alright, then got a tiny manga flow that was basically sounded like open headers, and now I've got a big case magnaflow and LOVE the way it sounds. Nice and quiet at idle but has tremendous bark when you hit the skinny pedal.

    Here is a pretty crappy cell phone video of it:

    That sounds great, real clean. thank you for the link.
    which magnaflow is that? I think I would like something just a touch more aggressive sounding at idle, but that is more or less what i'm after. A nice clean sound

    EDIT: does yours have the cats on, or did you leave them off?

    if you want more sound at idle, turn-down in front of the axle or go with 2-offroad proseries or magnaflow glasspacks
