Mufflers & Resonators
How does a muffler affect performance?
The primary function of a muffler is to reduce sound. However, the mufflers Accesspeed offers are designed to improve performance and fuel economy, while giving your vehicle a better sounding exhaust note.
How does a resonator affect performance?
A resonator tunes the exhaust note or sound of your exhaust system. Some resonators provide a crisp, throaty sound, while other resonators offer a deeper, rumbling sound.
What is the difference between a muffler and a resonator?
Resonators change your vehicle's engine sound, while mufflers reduce the volume. When you combine a muffler and resonator, you can fine-tune your exhaust sound to find that perfect combination that is pronounced, yet not too loud.
