Exhaust Resonators

Cancel out annoying cabin drone, eliminate harsh high-frequency exhaust rasp, and smooth out your vehicle’s acoustic profile with performance exhaust resonators. Installed inline along the mid-section of your exhaust system, a resonator works by targeting specific sound wave frequencies. As high-velocity exhaust gases pass through, sound waves bounce off the internal chamber walls or perforated core, creating destructive interference that cancels out harsh raspy tones without restricting overall exhaust gas velocity or robbing engine horsepower.

Upgrading to a high-flow performance resonator is the ultimate solution for tuning an overly loud or raspy exhaust setup—especially after installing high-flow downpipes, long tube headers, or cat-delete pipes. Whether you need a compact bottle-style resonator for tight undercarriage clearances or a larger oval resonator to maximize acoustic absorption on long highway cruises, adding a dedicated resonator refines your sound into a deep, aggressive tone. Explore straight-through perforated core resonators packed with heat-resistant ceramic or stainless steel wool dampening materials. Constructed from heavy-gauge T304 stainless steel and aluminized steel, find universal weld-in resonators available in 2.25-inch, 2.5-inch, 3-inch, and 3.5-inch pipe diameters.
