Compatible With Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, and GMC Savana 3500 applications in the listed left-side configurations. This part number, 19399, is a direct-fit exhaust replacement for vehicles that require the specified converter layout.

Key Features

• Exact-Fit design based on original equipment sample parts
• 3-bolt fixed flange inlet for a secure exhaust connection
• 3-inch outside diameter outlet
• 63-inch overall length
• Configured for OBDII emissions requirements
• Uses a high-quality emissions-reducing catalyst

Detailed Description

Davico Exact-Fit Catalytic Converter 19399 is engineered as a direct replacement for the specified Chevrolet Express and GMC Savana applications. The converter is built around OE sample-part dimensions and connection points to support proper fitment, while the catalyst formulation is selected to address emissions control needs on current OBDII vehicles. The 3-bolt fixed flange inlet and 3-inch OD outlet help maintain the intended exhaust routing and connection style.

This part number, 19399, is listed for 2003-2007 Chevrolet Express 2500 and Express 3500, plus 2003-2007 GMC Savana 2500 and Savana 3500 in the left position. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Failed catalytic converter efficiency codes
• Restricted exhaust flow from a worn converter
• Emissions test failures related to converter performance
• Exhaust leaks at the converter connection points
• Fitment issues from a non-OE-style replacement

Installation Notes

Verify the left-side application, inlet style, outlet diameter, and overall length before installation. The fitment notes also indicate emissions restrictions for California and New York applications with California emission systems, so confirm local compliance before ordering. Davico also notes use of decarbonizing induction kit 1540ea with this part.

Quality Assurance

Davico builds Exact-Fit Catalytic Converters from original equipment sample parts to support proper fit and function, and the catalyst is selected for emissions reduction on OBDII vehicles.
