Exhaust Resonators

Perfect your vehicle’s soundtrack with our professional range of exhaust resonators. Often called "hotdogs" due to their slim, cylindrical shape, resonators are essential for any custom exhaust build where sound quality is just as important as flow. By using specialized internal baffling and packing materials, these units cancel out annoying high-pitched frequencies and interior cabin drone without creating restrictive backpressure. Whether you are adding a resonator to a loud performance system or building a custom setup from scratch, our collection offers the perfect balance of flow and acoustic refinement.

1. What is the difference between a resonator and a muffler?

A muffler is designed to reduce the overall volume (decibels) of the exhaust. A resonator is a specialized echo chamber designed to cancel out specific sound frequencies—usually the annoying "hum" or "drone" heard at highway speeds—making the exhaust sound cleaner and deeper without necessarily making it quieter.

2. Where should a resonator be installed in the exhaust system?

For the best results in reducing drone, resonators are typically installed in the middle of the exhaust system, before the rear muffler. However, in some custom "straight-pipe" builds, they are used as the primary sound-deadening component to take the edge off a very loud system.

3. Will adding a resonator reduce my engine's power?

No. Most performance resonators feature a "straight-through" design, meaning the internal pipe is the same diameter as your exhaust system with no baffles to block the air. This allows for maximum gas velocity while still providing the acoustic benefits.

4. Can I use a resonator to pass a roadworthy noise test?

While a resonator helps clean up the sound, it is rarely enough on its own to bring a very loud car under the legal decibel limit. If your car is too loud, you likely need a high-quality Muffler. A resonator is best used as a finishing touch to improve the quality of the sound.
