Detailed Description

This Davico catalytic converter is part number 18596 and is built around OE sample parts to help maintain the original exhaust layout. The 66-inch overall length, 4-bolt fixed flange inlet, and slip-fit outlet reflect a factory-style configuration intended for vehicles that require a center-mounted converter in the exhaust path.
