Resonator 2.5in Inlet/ Outlet x 16in Long

The Resonator 2.5in Inlet/Outlet x 16in Long is a bottle-style acoustic resonator engineered to reduce exhaust drone and refine sound quality in performance automotive systems. Designed for drivers seeking a balanced approach to exhaust tuning, this resonator absorbs and cancels unwanted frequencies while maintaining clean exhaust flow. The 2.5-inch inlet and outlet sizing makes it compatible with common aftermarket exhaust configurations, offering a straightforward bolt-on solution for custom exhaust builds and street performance applications.

Built from titanium construction, the Resonator delivers superior corrosion resistance and durability under high-temperature exhaust conditions. Its 5.5-inch diameter body and 16-inch length provide optimal internal chamber volume for effective frequency attenuation without significant backpressure penalties. The bottle-style design uses internal baffling to separate and dampen resonance waves, allowing exhaust gases to pass freely while acoustic energy is dissipated through the titanium walls. This engineering approach minimizes restriction, making it suitable for naturally aspirated and moderately boosted applications where both sound control and flow efficiency are priorities.

Performance enthusiasts and custom exhaust builders benefit most from this resonator when targeting drone elimination on highway cruising without sacrificing aggressive tone during acceleration. Installation requires standard 2.5-inch clamped or welded connections, making it compatible with most universal exhaust systems and custom fabrication projects. Weighing 5.02 lbs, it adds minimal mass while occupying a compact 18 x 7 x 7-inch footprint, allowing flexible under-vehicle placement in tight engine bay configurations. The natural titanium finish resists corrosion and provides an OEM-quality appearance suitable for show vehicles and daily drivers alike.
