Buick Envision Catalytic Converter - Underbody - Magnaflow - Direct Fit - `17-`20 free shipping

Buick Envision Catalytic Converter - Underbody - Magnaflow - Direct Fit - `17-`20. This direct-fit underbody catalytic converter is designed as an OEM-grade replacement to maintain emissions compliance and restore proper exhaust function on compatible Buick Envision models.

Built to replicate factory flow and fit, this MagnaFlow spun‑body converter uses mandrel-bent tubing and corrosion-resistant stainless steel to provide long service life and reliable operation. Its compact, low-mass design promotes thermal efficiency, while precision metrology ensures an accurate match to OE dimensions so installation requires no cutting or welding when using the supplied hardware. Included gaskets help prevent exhaust leaks and simplify the swap.
