Aluminized 4 Inch ID Type 1 Resonator

The Aluminized 4 Inch ID Type 1 Resonator is a practical and efficient solution for eliminating unwanted resonance or noise at a specific RPM, commonly known as exhaust drone. Made of durable aluminized steel, this resonator features a 4-inch inlet diameter, 4-inch outlet diameter, 9-inch body diameter, 10-inch body length, and 16.5-inch overall length. It fits most makes and models and is sold individually. Unlike a muffler that reduces volume across all RPMs, this resonator specifically targets and eliminates unwanted noise, ensuring a quieter and more enjoyable driving experience.
