Which Perfromance Muffler is Right for My Vehicle?

An aftermarket performance muffler is designed to improve your vehicle's engine sound and performance. Often located near the rear axle, the muffler is connected to the exhaust pipe coming from the engine, and the exhaust tail pipe in your vehicle connects to the muffler's outlet. While most factory-installed mufflers are designed to reduce noise and vibrations from your car's exhaust system by limiting free air flow, performance mufflers can provide increased airflow to reduce exhaust back pressure, reducing the stress on your motor. This often increases your engine's performance, and allows exhaust to exit the engine as quickly and efficiently as possible. Performance mufflers can also be installed to produce better sound in performance vehicles. Some performance mufflers are designed specifically to produce a deep, throaty exhaust tone that makes your vehicle sound more aggressive and powerful. When choosing a performance muffler, selecting the correct exhaust diameter is important to simplifying installation and ensuring the most straightforward installation, as aftermarket exhaust may be larger in size than the original exhaust on your vehicle. In some cases, complete exhaust systems that are designed to be bolted or welded together may also be available to help make increasing horsepower and customizing your vehicle even simpler.
