Anyone ran db tests before and after muffler swaps??
Anyone ran db tests before and after muffler swaps??
Just wondering if anyone has done db testing of the stock muffler vs different muffler, mainly the Donaldson 51" I would really be interested in the idle, 65mph and pulling 10k trailers.
Wot to me is not that big a deal, since you are not usually full throttle for long then it don't much matter how loud it is
If no one has done this, I might have to mess around with it at some point.
