Ultra Quiet Resonator 3.5in Inlet/Outlet

The Ultra Quiet Resonator 3.5in Inlet/Outlet is a premium exhaust silencing component designed for builders and enthusiasts who demand refined acoustics without sacrificing flow. This polished stainless steel resonator fits seamlessly into custom exhaust systems where noise reduction and aesthetic appeal are equally important. Built by VIBRANT PERFORMANCE, a recognized leader in exhaust technology, this unit addresses the need for controlled sound dampening in both street and performance applications.

The resonator features centered 3.5-inch inlet and outlet ports, engineered to minimize turbulence and pressure loss while absorbing high-frequency noise through internal resonance chambers. Its round-body construction (6.5 x 4.75 x 9.75 inches) and extended 13.75-inch overall length provide optimal internal volume for effective sound attenuation. The polished stainless steel construction ensures durability against corrosion and heat cycling, while the smooth finish maintains visual quality under vehicles. This design principle—using resonance rather than restrictive baffles—preserves backpressure characteristics critical for engine performance.

Ideal for exhaust system builders, custom hot rod fabricators, and owners seeking OEM-quality sound control, this resonator works best in mid-pipe or secondary muffler positions where it complements primary silencers. It weighs 7.35 pounds and is sold as a complete unit, ready for direct weld-in or bolt-on installation with matching 3.5-inch piping. Compatibility depends on your exhaust system configuration; verify inlet and outlet diameter sizing before purchase to ensure proper fitment.
