Racing Go-Kart Mufflers

Mufflers dampen the sound of vehicle emissions and reduce the engine noise caused by pistons and valves. A muffler works by combining sound waves inside its chamber to cancel them out, resulting in a quieter drive. The chamber of a muffler has several channels and holes that direct gasses to reduce exhaust pressure and redirect sound waves into each other. They are often built from steel and aluminum with enough durability to resist both the intense heat and the chemical emissions caused by the vehicle’s engine.

At NR Racing, you can find a large selection of exhaust mufflers and silencers for racing go-karts. We carry kart parts from some of the best brands such as RLV, Genuine Honda, Briggs, and more.

If you are racing near a residential area, your vehicle may be subject to certain noise ordinances. Be a good neighbor and avoid unwanted complaints with mufflers designed for racing karts. We also have the supporting hardware you need to keep a muffler in place and locked tightly. Use muffler and exhaust clamps to tighten these parts so they won't rattle even at high speeds.
