This catted pipe is designed to reduce harmful emissions at the same time, maintain excellent horsepower and torque performance. In addition, it has a high-flow design that won’t interfere with engine codes in your truck thus eliminating that annoying check-engine light (CEL) on the dashboard.

High-Quality Build. Manufactured to comply with strict industry standards, this Green Catted Dual Connection Pipe is crafted from high-quality materials using state-of-the-art technology. Featuring a 16-gauge stainless steel construction, this connection pipe will last years of tough and rugged use. This can handle exhaust temperatures of up to 1500°F so you won’t have to worry about high-temp exposure.
Bolt-On Installation. This catted dual connection pipe uses the OEM pipe outlet to ensure easy installation. Installation will take less than an hour and requires light to moderate mechanical skills.

For limitations and exclusions, please refer to the manufacturer’s website.
Certification. The Kooks 3-Inch Green Catted Dual Connection Pipe is compliant with EPA’s emission testing standards. However, this pipe is not CARB-Certified and is therefore not legal for sale or use on any vehicle registered in California.
