Product Details

Davico Exact-Fit Catalytic Converter 19587 is engineered for direct replacement where a rear catalytic converter is required. The OE-sample-based design helps maintain proper alignment with the exhaust system, while the catalyst formulation is selected to reduce emissions on current OBDII-equipped vehicles. This part is a fitment-specific solution for 2009-2015 Buick Enclave rear, 2009-2015 Chevrolet Traverse rear, 2009-2015 GMC Acadia rear, and 2009-2010 Saturn Outlook rear applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

• Replacing a failed rear catalytic converter

• Repairing a leaking or rusted flange connection

Installation Notes

Verify rear-position fitment before installation and confirm the exhaust uses 2 bolt fixed flange connections at both inlet and outlet. Check the vehicle’s emissions certification and state requirements before purchase; this part is not legal for use in California and is illegal for installation in New York on vehicles equipped with California emission systems. For best results, compare the existing converter length, flange style, and mounting location to the vehicle application before beginning the repair.
