A quieter cab makes long tows and highway miles a lot more comfortable. This universal quiet tone muffler installs on 4 in. exhaust tubing and greatly reduces cab noise while keeping flow high, and its T409 stainless steel construction stands up to corrosion better than plain or aluminized steel on trucks that work year-round.
