Kooks Headers 13623300 3" Stainless Steel GREEN Catted Turbo Downpipes

The Kooks Headers 13623300 features 3-inch stainless steel GREEN catted turbo downpipes designed specifically for 2017-2020 Ford F-150 Raptor EcoBoost 3.5L V6 applications. These downpipes include Kooks' proprietary "GREEN" high-flow catalytic converters that dramatically increase exhaust flow compared to restrictive factory converters, unlocking significant performance gains for your turbocharged engine.

Key Features:

• Constructed from 3-inch mandrel-bent 304 stainless steel for superior durability and resistance to rust and corrosion
• GREEN catalytic converters are EPA-certified and rated for forced induction applications producing up to 750 rear-wheel horsepower
• Direct bolt-on installation that connects to OEM exhaust with no additional parts required
• Made with T304 aircraft-quality stainless steel
• 48-state EPA-certified and street legal (not CARB compliant)
• Handcrafted in the USA
• All necessary hardware included

The factory downpipes on turbocharged engines feature smaller diameter piping that restricts exhaust flow and increases backpressure. Kooks addresses this by replacing the restrictive components with larger diameter, high-flow downpipes that enable your EcoBoost engine to breathe freely. The smooth mandrel bends maintain optimal airflow while the larger diameter helps lower exhaust gas temperatures by allowing gases to expand. The result is improved horsepower, torque, and throttle response, especially when paired with performance tuning.

Kooks products are backed by a limited lifetime warranty to the original purchaser. Note: These products are not legal for sale, installation, or use on licensed vehicles in California and do not meet CARB compliance.
