Product Details
The Polar Diesel 4" muffler is listed by its 4-inch pipe size rather than for one vehicle, and it sits in the exhaust line of a diesel truck to quiet the exhaust.
A muffler is a chamber in the exhaust system that reduces engine noise as exhaust gas passes through it; its internal design shapes how the exhaust sounds.
