Ultra Quiet Resonator 2. 5in inlet/outlet

The Ultra Quiet Resonator 2.5in inlet/outlet by Vibrant Performance is designed for automotive builders seeking to reduce exhaust noise without significantly affecting flow characteristics. This resonator is particularly useful in custom exhaust systems where drone and noise can be problematic during extended driving. It is suitable for various applications, including street machines, weekend cruisers, and performance daily drivers.

The resonator features a design that aims to mitigate aggressive drone in the 1500–2500 RPM range, utilizing chambers intended to dampen specific resonance frequencies. With a 2.5-inch inlet and outlet, it aligns with modern performance piping standards, ensuring minimal flow restriction while providing sound attenuation. Constructed with mandrel-bent tubing and welded internals, it is built to withstand thermal cycling and vibration.

This resonator is ideal for systems that include cat-back exhausts, headers, or complete custom builds where controlling drone is essential. Mechanics and fabricators appreciate its compatibility with existing systems, as the straight-through 2.5-inch piping allows for standard mandrel bends and slip-fit connections. It can be effectively used upstream of the muffler to enhance overall exhaust performance.
