The Kooks Headers KSHR300-10 universal round muffler is designed for high-performance street, race, and off-road exhaust applications. Manufactured in the USA from T304 aircraft-quality stainless steel, this muffler delivers durable construction, corrosion resistance, and a polished appearance. Its compact round design supports flexible installation in custom exhaust systems while helping provide a balanced exhaust tone and reliable performance.

Featuring a 3-inch inside-diameter inlet and outlet, the KSHR300-10 is suitable for exhaust systems built around 3-inch tubing. The muffler has a 10-inch body and a 15-1/2-inch overall length, with a 4-1/2-inch outside-diameter body. It is sold individually, making it a practical choice for custom builds, replacement applications, and performance exhaust projects requiring a single muffler.

Kooks Headers has been family owned and operated for three generations, with products developed through dyno and race testing for dependable fitment and performance. The KSHR300-10 is backed by a limited lifetime warranty to the original purchaser. Verify available clearance and exhaust-system compatibility before installation, as this universal muffler does not include vehicle-specific fitment hardware.
