Kooks 3" High Output GREEN Catted Front Connection Pipes - Ford Mustang 5.0L & Shelby GT500

Designed for high-performance Mustang builds, the Kooks 3" Stainless Steel High Output GREEN Catted Front Connection Pipes deliver improved exhaust flow while maintaining catalytic converter functionality. These connection pipes are ideal for aggressive street and forced-induction setups looking to support higher horsepower without sacrificing durability.

Built from 3" 16-gauge 304 stainless steel, these front connection pipes feature a ball-and-socket style connection to Kooks long tube headers for proper alignment and sealing. The integrated Kooks High Output GREEN catalytic converters use a 4-1/2" 300-cell high-flow substrate, making them suitable for forced induction applications. This system is designed to pair with Kooks headers and OEM adapters or a Kooks connection-back exhaust and does not connect to the factory exhaust system.
