Eastern Convertors 50458 Catalytic Converter with Integrated Exhaust Manifold - Front

Direct-Fit Catalytic Converter Manifold

Eastern Convertors 50458 is a direct-fit catalytic converter with integrated exhaust manifold built for specific GM applications. It is engineered to match OE dimensions and fitment for a straightforward replacement on the front exhaust position.

The Eastern Convertors DIRECT FIT line focuses on OE-style fitment and consistent manufacturing for repair work that needs accurate alignment at the manifold and converter interface. This part is built with a Federal / EPA direct-fit manifold design and uses ECO GM catalyst chemistry.

Key Features

Detailed Description

Eastern Convertors 50458 is made for front-position exhaust service on the 2004-2006 Chevrolet Colorado, 2004-2006 GMC Canyon, and 2006 Isuzu i-280. It is a direct-fit catalytic converter with integrated exhaust manifold, which helps maintain the original exhaust layout and connection points for these applications. The DIRECT FIT product line is built around OE dimensions and fitment consistency, making it a practical choice when replacing a worn or failed manifold converter assembly. If you are searching for a catalytic converter manifold for a 2004-2006 Chevrolet Colorado front, or a direct-fit exhaust manifold converter for a 2004-2006 GMC Canyon front, this part number 50458 matches those vehicle listings.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Failed catalytic converter efficiency codes
• Exhaust leaks at the manifold-to-pipe connection
• Cracked or damaged integrated manifold assemblies
• Restricted exhaust flow from a deteriorated converter substrate
• Fitment issues caused by non-OE-style replacement parts

Installation Notes and Tips

Verify the vehicle is a Federal / EPA application before ordering. This part is not for sale or use in California, Colorado, Maine, or New York for vehicles with California emissions. Confirm the front exhaust position, the 7-bolt welded inlet, the 3-bolt welded outlet, and the single O2 sensor port before installation. Check gasket surfaces, exhaust flange condition, and sensor threads during replacement to help ensure a proper seal and accurate fit.

Quality Assurance

Eastern Convertors uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions and fitment. The NANO substrate chemistry is used to support efficient catalyst loading and consistent converter performance within the intended Federal / EPA application range.
