Nissan Pathfinder muffler
Muffler is a component of the exhaust system that reduces noise with the aid
of baffling or another internal design. Vehicles usually come with two twin mufflers.
The high performance mufflers allow exhaust gasses to pass through more easily
than with those that ahs low performance designs, therefore producing less backpressure.
But there are also mufflers which make louder noise than the factory one. Still,
you can find high-performance products that are as quiet as the factory mufflers.

Mufflers affect the amount of noise that passes out through a car's tail pipe,
so as the amount of noise being transmitted through the floor and unto the passenger
compartment. Nissan Pathfinder mufflers will have values depending on the engine
that it will support with the different trims and models of Nissan Pathfinder.
