    I know this is opposite of what most truckers want, but I need to quieten my truck down. My hearing has deteriorated over the years such that while I have trouble hearing speech distinctly, loud noises, trucks, (my JD tractor also) are very painful and annoying. I had a 98 volvo 20 years ago that was almost as quiet as a car in the cab. My 04 ws lowmax has a 5" pipe off the turbo which then goes into a 6" y and splits to 2 - 6" mufflers right behind the cab doors. The mufflers are not original, they were cat cons and pretty quiet, but these are just big cans that don't do a lot. Ideally I would run it all the way back and put them behind the sleeper with a new set of mufflers. Pretty big job, more time and money than I want to invest at this point. What about this idea though, what if I buy 1 good muffler, put it on the passenger side in place of the existing no good can, and simply block off the driver side stack underneath? Shouldn't hurt to run a single 6" exhaust? many trucks have just 1-5". Engine is a 550hp C 15. Wouldn't change overall appearance either. Thoughts? TIA.

    You could definitely do this. Yes.
    Or another option is find some mufflers that actually muffle.

    Look up Donaldson silent partner mufflers.
    They are the best ones they make and very quiet
    HoneyBadger67 and 04 LowMax Thank this.

    New Petes have two stacks but only one exhaust. There shouldn't be any reason why your Star couldn't operate the same way.

    Or you could just make a weed burner out of it...?
    04 LowMax Thanks this.

    Every T880 with twin stacks the driver's side is just a dummy.

    Myself I'd just plumb in a single pipe through to the passenger side and just disconnect the driver's side at the elbow, out of sight.
    04 LowMax Thanks this.
