What Are Exhaust Resonators?

An exhaust resonator helps cancel higher engine frequencies before they arrive at the muffler. The result is the ability to use a less restrictive muffler that still acts as the final component in quieting your exhaust, which increases fuel efficiency and power. Over time, exhaust resonators can rust and develop cracks or other damage, which can cause an exhaust leak. Bad exhaust resonator symptoms include loss of power, a change in the sound of your vehicle, and signs of an exhaust leak, which may sound like a ticking noise during engine operation and can leave soot or other residue around the leaking connection or component in the exhaust system. If you suspect you have an exhaust leak or a damaged resonator, it's a good idea to check your exhaust system components for any damage. Leaks from the exhaust system can make their way into the cabin at idle, and carbon monoxide in the exhaust can pose a health hazard to you and your passengers if this is not resolved. If you need a new exhaust resonator or if you're just interested in upgrading your current exhaust system, O'Reilly Auto Parts carries exhaust resonators and related parts and tools to help you make your repair or upgrade as simple as possible.
