Although pipe diameter and mandrel bending will 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 car or truck quiet has priority over performance, because the quality of the sound coming out of the speakers is much more important to the average driver than what comes out of the tailpipe.

    Featured Brands

    Our performance mufflers are designed for enthusiasts, not average drivers. We know that you not only want better exhaust flow for more horsepower, but you want your car or truck to have a particular exhaust tone. That’s why we offer a huge selection of mufflers from the top performance exhaust manufacturers. Whether you’re racing or towing a boat, have a screaming turbo 4-cylinder or big V8, we have the mufflers to give you the power and sound you want.

    Maximizing exhaust flow while creating the desired exhaust tone takes hard work. Our manufacturers perform extensive R&D work with airflow and acoustical test equipment, as well as dyno and real world on-vehicle testing. And just as there are different ways to brew beer, several muffler designs are used to achieve performance goals. Chambered mufflers have internal chambers that reflect and cancel out sound waves without reducing exhaust flow; turbo mufflers have several perforated tubes to reduce sound while reducing backpressure; and straight through mufflers have a perforated tube surrounded by sound absorbing packing.

    Regardless of design, it’s the end result that counts. No matter what you drive or what you do with your vehicle, we have mufflers to suit your needs. If you tow a trailer with your truck you may want more pulling power but with just a moderate exhaust rumble and minimal resonance inside the cabin. Or you may have a big inch street machine and want the least restriction and most aggressive sound available. Many race tracks and racing organizations have decibel restrictions which require mufflers that reduce noise but with the least amount of restriction possible. We offer mufflers for each of these applications and more.

    Besides getting the right power and sound, the performance mufflers on our digital shelves are also available in a wide range of physical sizes and inlet and outlet diameters, so you can get the muffler that perfectly fits your exhaust system and space requirements. We offer both vehicle specific and universal mufflers; compact, low profile, and slimline designs; as well as collector mufflers. And you can buy any of our mufflers with the confidence that they’ll deliver the power and sound you want today and well into the future, because each is constructed from long lasting, durable stainless steel or aluminized steel.

    Good Muffler
    Not quiet like OEM, but better than a straight through muffler.
