Kooks R250-14 Universal 2.5-Inch Round Muffler – 14" Body Polished Stainless Steel

The Kooks universal 2.5-inch round muffler delivers proven straight-through performance in a compact 14-inch polished T304 stainless steel body, providing aggressive tone with minimal backpressure for custom exhaust builds, header test pipes, or race applications up to 600+ HP. Featuring a perforated core wrapped in stainless steel packing, this muffler absorbs high-frequency noise while allowing free flow for maximum horsepower and torque.

With 2.5-inch center/center inlet and outlet, the fully welded construction resists corrosion and heat up to 1,800°F, while the mirror-polished finish adds show-quality appearance under the vehicle. At only 14 inches long and 4 inches in diameter, it fits tight spaces where longer mufflers won’t, making it ideal for classic cars, hot rods, or turbo setups needing short, high-flow silencing.

For builders demanding race-proven flow with street-friendly tone in a compact package, the Kooks R250-14 is the universal performance muffler trusted on thousands of custom exhaust systems.
