Hushpower II Resonator - 2.00 In/Out 12L

The Flowmaster Hushpower II Resonator with 2.00-inch inlet and outlet is a performance muffler designed to reduce exhaust noise while maintaining power output in automotive applications. This resonator features a 12-liter chambered design that targets specific frequency ranges, delivering measurable sound attenuation without excessive backpressure. The center-inlet/center-outlet configuration ensures compatibility with a wide range of exhaust systems.

Constructed with stainless steel to resist corrosion in various environmental conditions, this resonator measures 24.75 inches in length with an oval body profile (approximately 12 x 5 inches), engineered to fit tight exhaust installations while preserving flow dynamics. At 6.15 pounds, it delivers acoustic performance without adding significant weight to the exhaust system. The 2-inch tubing diameter matches common aftermarket exhaust specifications and allows for straightforward installation into existing systems or new builds.

This Hushpower II resonator suits builders and enthusiasts seeking exhaust noise reduction for street vehicles, weekend drivers, or those navigating noise ordinances without sacrificing performance. The stainless steel construction resists rust and thermal degradation, providing long-term durability in both wet climates and high-temperature underhood environments. Flowmaster resonators are engineered to work independently or as part of a complete exhaust system, offering flexibility for custom installations.

The Hushpower II line represents Flowmaster's dual-chamber resonator technology, which separates and absorbs specific exhaust harmonics rather than relying on a single silencing approach. This targeted methodology preserves mid-range and high-rpm power characteristics while reducing cabin noise and external sound signature—a balance that appeals to drivers needing quieter operation without dyno power loss.
