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.

When an engine operates, both exhaust gas and the sound waves created by engine combustion travel through the exhaust system. Factory mufflers are constructed to effectively quiet the sound, but in the process substantially restrict exhaust flow, which creates excessive backpressure that can significantly reduce an engine's power output. Replacing the restrictive OE muffler with a performance muffler will increase flow and allow your engine to produce the power it's capable of, and at the same time provide an exhaust note that will let everyone know your ride isn't just another stock machine.

But creating a performance muffler takes a lot of hard work, because while everyone wants increased exhaust flow and more power, we don't all want the same exhaust tone. Modern performance muffler fabrication starts with sophisticated computer aided design and proprietary software. Our manufacturers perform extensive R&D work with airflow and acoustical test equipment, as well as dyno and real world on-vehicle testing. Several muffler designs are used to achieve performance and sound 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 do with your vehicle, we have mufflers to suit your needs, from the top performance exhaust companies. 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. If you tow a trailer with your truck you may want more pulling power but with just a moderate 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 minimum restriction. 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 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.
