Product Overview

AP Exhaust 98237 is engineered around ARISTO substrate chemistry and modern manufacturing methods to deliver consistent converter construction and OE dimensions. For owners searching for a 3-inch inlet/outlet universal catalytic converter for a Chevrolet C1500, GMC K2500, or similar California Pre-OBDII truck or van, this unit provides a direct emissions-focused solution with CARB compliance identified by EO D-280-94. This part cross-references AirTek, Inc. (e.g., D-280-94) for the same application.

Common Issues This Part Helps Address

• Failed emissions testing due to a worn or non-compliant converter
• Restricted exhaust flow from a deteriorated catalytic substrate
• Fitment problems caused by incorrect body size or neck dimensions
• Replacement needs on California Pre-OBDII Chevrolet and GMC exhaust systems
• Converter replacement for vehicles requiring CARB-compliant emissions equipment

Installation Notes and Tips

Verify the vehicle’s emissions requirements, pipe diameter, and available installation space before ordering. Confirm that the 3.00" ID neck inlet and outlet, 16.5-inch overall length, and large oval body match the exhaust layout on your Chevrolet or GMC application. Because this converter has no O2 sensor ports or air tube provisions, it should be selected only for systems that do not require those features.

Quality Assurance

AP Exhaust builds this converter using automated workstations, spinner welding equipment, and high-speed production lines to maintain consistent dimensions and fitment. The stainless steel body and ceramic substrate are paired with CARB compliance under Executive Order D-280-94 for the listed applications.
