Exhaust Resonators - 2" & 3" Inlet

Resonator or muffler?

A muffler lowers overall volume. A resonator targets a narrow band of frequencies, mainly the low drone you hear in the cabin at constant speed. Many systems run both: the resonator handles drone and the muffler sets the overall sound level.

How a straight-through resonator works

Gas flows through a perforated core with no baffles in its path, so flow stays high. The body around the core absorbs the sound waves that cause drone before they reach the tailpipe.

Choosing the right resonator

Match the inlet to your pipe's outside diameter. A longer or larger body generally takes out more drone, so fit the biggest one that clears your chassis and heat-sensitive parts. Stainless bodies, such as 430 stainless, last far longer than mild steel under the vehicle.

FAQ

What's the difference between a resonator and a muffler? A muffler lowers the overall volume of the exhaust. A resonator targets specific frequencies, mainly the drone at highway speed, while keeping flow high.

What does a resonator do? It cancels the low, booming drone that builds inside the cabin at constant cruising speed. Gas passes straight through a perforated core while the body absorbs the problem frequencies.

Will a resonator reduce exhaust drone? Yes, drone is what resonators are designed for. A longer or larger body generally gives more drone reduction, so fit the largest one that suits the space you have.

Can I run a resonator and a muffler together? Yes, and many systems do. The resonator deals with drone and the muffler controls the overall sound level.
