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.
