Beyea mufflers are a "sound" decision. Race cars by nature are noisy, and decreasing the sound doesn't necessarily mean declining performance. These fabricated lightweight steel mufflers are effective and reliable choices for your Circle Track racer. Unfortunately, most race tracks have sound compliance rules. Fortunately, Beyea mufflers will allow your Circle Track car to comply and perform.
