Mufflers & Resonators

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 internal combustion engine exhaust contains poisonous Carbon Monoxide (CO), a noxious, colorless and odorless gas that in sufficient concentrations can cause severe illness and even death. 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, usually 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. Many mufflers and resonators come with hanger brackets attached and some come integrated with a section of exhaust pipe.

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, including hanger placement if so equipped, and their internal configuration is designed to give you OE-type sound quality and level of performance. Universal mufflers may require some cutting and fabrication for installation.

Although pipe diameter and mandrel bending have a significant effect on exhaust flow, by far the most important factor in improving exhaust flow, and sound, is the muffler. When factory mufflers are designed, making the vehicle quiet has priority over performance, because the quality of the sound from the speakers is much more important to the average driver than what comes out of the tailpipe. Our performance mufflers are designed for enthusiasts, not average drivers, because we know you not only want better exhaust flow for more horsepower, you want your car or truck to sound awesome.

Besides getting the right power and sound, the performance mufflers on our digital shelves are also available in a variety of shapes, dimensions, and configurations, with a wide range of inlet and outlet diameters, so you can get the muffler that perfectly fits your exhaust system and space requirements. Most are universal fitment and ideal for custom exhaust building, but we also have vehicle specific mufflers. Our selection includes round, oval, compact, low profile, and slimline designs; as well as collector mufflers, mufflers with integral exhaust tips, and much more. Our mufflers will deliver the power and sound you want today and well into the future, because each is constructed from long lasting, durable materials like stainless steel or aluminized steel.
