Detailed Description

The Davico Dealer Alternative Exact-Fit Catalytic Converter line is engineered as an alternative to OE replacement converters when the application calls for a direct-fit emissions component with upgraded substrate capacity.

• Restoring exhaust flow and oxygen storage function in the converter assembly.
• Serving as a direct-fit option for older Nissan and Infiniti exhaust systems.
