Resonator 2.5in Inlet/ Outlet x 16in Long

The Resonator 2.5in Inlet/Outlet x 16in Long from Vibrant Performance is a straight-through exhaust resonator designed to reduce exhaust drone and refine engine tone without restricting flow. This component addresses a critical challenge in performance and street applications: controlling unwanted resonant frequencies that build up in the exhaust system while maintaining peak horsepower and torque delivery. Built for builders and mechanics seeking a balanced solution between acoustics and performance, the resonator integrates seamlessly into custom exhaust builds and factory-to-modified transition systems.

This 16-inch resonator features dual 2.5-inch inlet and outlet ports, enabling compatibility with common mid-pipe and cat-back configurations across various platforms. The straight-through design utilizes internal sound-absorbing material to target and dampen specific frequency ranges responsible for cabin drone, particularly during highway cruising and steady-throttle operation. The compact 18 x 7 x 7-inch envelope and 5.02-pound weight make installation straightforward in tight engine bays, while the robust construction ensures long-term durability under thermal and vibration stress. Vibrant Performance's engineering focuses on maintaining backpressure curves that support scavenging efficiency rather than adding harmful restriction.

Technicians and enthusiasts upgrading factory exhausts, building turbo kits, or transitioning to cat-back systems rely on the Resonator 2.5in Inlet/Outlet to preserve drivability and reduce fatigue from persistent exhaust noise. Installation works best when positioned between a high-flow catalytic converter and secondary muffler or as part of a dual-exit configuration. The 2.5-inch bore sizing pairs well with 2.5-inch mandrel-bent piping and offers excellent results on turbocharged four-cylinder platforms, naturally aspirated V6 engines, and light-duty truck applications where resonance control enhances both comfort and perceived refinement without compromising flow dynamics.
