Detailed Description

Bosal part number 079-5254 is a BRExhaust Premium Load Federal / EPA compliant direct-fit catalytic converter designed for 2001-2002 Chevrolet Express 2500, 2001-2002 Chevrolet Express 3500, 2001-2002 GMC Savana 2500, and 2001-2002 GMC Savana 3500 left-side exhaust service. It uses stainless steel construction with a ceramic substrate to support long-term durability in exhaust-system environments. The direct-fit layout helps maintain the original exhaust routing and sensor placement, including pre- and post-converter oxygen sensor locations.

This converter is intended for vehicles operating under Federal OBDII EPA emissions standards and is built for straightforward bolt-on installation without cutting, welding, or fabrication. If you are replacing a worn or failed converter on a Chevrolet Express or GMC Savana van, 079-5254 provides an application-specific replacement that matches the listed fitment and exhaust configuration.

What This Part Helps Address

• Check engine light concerns related to catalytic converter efficiency
• Failed emissions inspection results on Federal OBDII vehicles
• Restricted exhaust flow caused by a deteriorated converter
• Corrosion-related exhaust leaks at the converter assembly
• Fitment issues from using a universal-style replacement

Installation Notes

Install on the listed left-side applications only: 2001-2002 Chevrolet Express 2500, 2001-2002 Chevrolet Express 3500, 2001-2002 GMC Savana 2500, and 2001-2002 GMC Savana 3500. The bolt-on inlet and clamp-on outlet are designed for direct replacement, and the included clamp and mounting hardware support installation. Verify oxygen sensor routing and exhaust alignment before final tightening.

Part number 079-5254 should be matched to the vehicle’s emissions configuration and side-specific exhaust layout before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Bosal BRExhaust converters are built with stainless steel construction and a ceramic substrate to support durable service in emissions-system applications. The Federal / EPA compliant design is engineered for OBDII vehicles that require a direct-fit catalytic converter replacement.
