Stainless Resonator

The Stainless Resonator by AFE POWER (MPN 49-36428) is a premium exhaust component engineered for serious enthusiasts who demand refined sound control without sacrificing flow. This resonator targets the mid-range drone frequencies that plague stock exhaust systems during highway cruising, making it an essential upgrade for both street and performance builds. Whether you're running a naturally aspirated engine or a forced-induction setup, a quality resonator preserves backpressure while eliminating the fatiguing cabin noise that comes with aggressive catback systems.

Constructed from premium stainless steel, this resonator delivers superior corrosion resistance and longevity compared to mild steel alternatives—critical for vehicles exposed to road salt, moisture, or high-heat cycling. The 10 x 10 x 48-inch chamber dimensions are optimized to absorb and attenuate specific frequency bands without creating excessive back-pressure that would rob horsepower or torque. AFE POWER's engineering approach uses internal baffling and acoustic dampening principles to convert resonant energy into heat dissipation, resulting in a noticeably quieter exhaust note while maintaining scavenging efficiency and exhaust velocity needed for peak engine performance.

This stainless resonator works best on modified vehicles running larger displacement engines, turbochargers, or superchargers that generate high exhaust flow rates and pronounced drone characteristics. Installation is straightforward for anyone with basic exhaust work experience—the 34.54-pound unit bolts inline between your downpipe and catback system using standard clamps and flanges. Verify your vehicle's exhaust diameter and mounting points before ordering to ensure seamless integration; most applications require minimal fabrication and no engine tuning adjustments.
