Resonators

Resonators are an essential component in fine-tuning your exhaust note. Installed inline within the exhaust system, a resonator uses a perforated tube surrounded by sound-absorbing material—typically stainless steel wool or fiberglass—to target and cancel out specific resonant frequencies that cause drone and rasp. The result is a refined, deeper tone without introducing excessive backpressure or restricting flow. Whether you're replacing a rusted factory unit, eliminating drone from an aftermarket cat-back, or building a custom exhaust from mandrel bends, the right resonator makes the difference between an annoying cabin hum and a comfortable, aggressive sound. Our collection includes straight-through, chambered, and packed designs in a range of inlet/outlet diameters, overall lengths, and case sizes to match your piping and sound goals. All resonators are constructed from durable materials like T304 stainless steel for corrosion resistance and long life. Use the provided specifications to confirm diameter, overall length, and case dimensions fit your exhaust layout.
