The exhaust system has two functions: routing the exhaust gas from the engine to the rear of the vehicle and away from the cabin, and quieting the pressure waves created by engine combustion. The first is essential for occupant safety, because exhaust gas contains poisonous Carbon Monoxide (CO), and the second is necessary to prevent excessive noise that could become irritating to you and annoying to other drivers and pedestrians, and also violate the law.

Mufflers and resonators are the exhaust system components tasked with reducing noise. All vehicles have mufflers, but resonators are used only on certain applications, generally luxury cars where a particularly quiet exhaust tone is desired. A muffler has an oval or cylindrical housing with an inlet and outlet that enables it to be plumbed into the exhaust system. Resonators have similar construction and are usually located at the rear of the vehicle.

While the internal construction will vary according to exhaust system manufacturer and vehicle application, in general a muffler has perforated tubes and baffled chambers inside the housing, which are designed to cancel out the sound waves from the engine. Some mufflers also include packing or insulation to absorb pressure pulses. Anything that restricts exhaust flow and creates backpressure, including these sound reducing features, can reduce power. A properly designed muffler, like the ones on our digital shelves, provides quiet vehicle operation while keeping power robbing restriction and backpressure to a minimum.

Muffler and/or resonator replacement may be necessary due to perforation caused by rust and corrosion, physical damage, or internal failure. Mufflers rust from the outside from exposure to the elements and road salt, but they can also rust from the inside from condensation, particularly on vehicles driven short distances. In its position on the underside of the vehicle, the muffler is subject to impact from obstacles and road debris that could cause physical damage. Such damage and internal structural failure can result in excessive restriction and loss of power.

Because perforation with the resulting exhaust leaks and noise is such a common cause of muffler failure, we offer mufflers constructed from corrosion resistant stainless steel and aluminized steel. You can count on them to deliver many years and miles of reliable, quiet performance. These mufflers come in both direct fit and universal versions. Our direct fit mufflers are specifically designed for each vehicle application. They have the same physical dimensions as the original equipment mufflers for easy installation, and their internal configuration is designed to give you OE-type sound quality and level of performance.

    Regardless of whether you're shopping for a simple replacement muffler that delivers original equipment (OE) sound and performance or an upgraded muffler which provides a deeper growl with increased power through freer exhaust flow, you'll see choices between "direct fit" mufflers and "universal" mufflers. In this article, we'll help you understand the differences between these two styles so you can make a more informed purchase.
