Buick Regal Catalytic Converter - Magnaflow - Direct Fit OEM Grade - `11-`13 is a direct-fit replacement catalytic converter engineered for 2011–2013 Buick Regal models. It is an OEM-grade MagnaFlow unit designed to restore proper emissions control and exhaust flow with a straightforward installation.
This MagnaFlow catalytic converter is built using mandrel-bent tubing and high-strength stainless construction to resist corrosion and preserve factory-like flow dynamics. Designed with 3D-scanned metrology to match OEM fit and geometry, the unit is intended to simplify replacement and reduce the chance of drivability codes when replacing a failed factory converter. Hardware and gaskets are included to minimize fuss with corroded original parts, and the direct-fit design allows DIY installation with the right tools—no cutting or welding required. This part is manufactured to meet Federal/EPA emissions requirements; state rules differ, so verify local regulations before purchase or installation.
