Product Description

The Kooks KO300-12 Universal Oval Muffler is a performance-oriented exhaust component designed for custom 3" diameter exhaust systems. Its polished 304 stainless steel oval body and center inlet/center outlet configuration make it versatile for a wide variety of custom exhaust layouts. This high-flow muffler smooths exhaust pulses while maintaining strong airflow, contributing to a deeper, more aggressive tone compared to many restrictive OEM components.

With a 12" long muffler body and universal design, the KO300-12 can be welded into custom exhaust builds on street cars, track cars, or performance vehicles where a 3" muffler is desired. Due to its universal nature, installation typically requires welding or custom exhaust fabrication. The stainless steel construction ensures corrosion resistance and long-lasting performance. Ideal for exhaust builders, fabricators, and performance enthusiasts looking to tailor the sound and flow of their system.
