ATP Exhaust Manifold with Catalytic Converter

The ATP Graywerks Exhaust Manifold with Integrated Catalytic Converter (also called an exhaust manifold/catalytic converter or manifold-converter) is an OE-style replacement. It combines the exhaust manifold and catalytic converter in one assembly. It is a proven repair for a failed catalytic converter that causes a check engine light or higher emissions.

Key Features:

• Direct OE replacement: Each unit is developed from the original part's specifications, so it lines up, installs and flows like the factory unit.
• Quality materials: Built from high-grade metals suited to each application, ranging from grey iron to ductile iron and stainless steel, with precious metals in the catalyst for long-lasting emissions performance.
• Machine-finished flanges: Flanges are machined flat so they mount evenly and resist leaking.
• OBD-II tested: Application testing is designed to meet the demands of the vehicle's On-Board Diagnostic computer, helping clear catalyst-related check engine lights and restore correct emission levels.
• Hardware: Gaskets and mounting hardware are included on many part numbers. The exact contents vary by part number.
• Warranty: Many part numbers carry a limited 5-year warranty.

A cracked or leaking manifold can allow exhaust gases to escape. Replacing it with an ATP Graywerks manifold-converter restores exhaust sealing and flow, and it helps the vehicle meet emissions standards. Emissions certification, including CARB approval, depends on the part number, so check the individual listing.
