The MagnaFlow direct-fit catalytic converter for 2010–2012 Buick LaCrosse 3.6L (and select 2010 LaCrosse 3.0L applications) replaces the OE unit to help keep the check-engine light off and meet Federal/EPA emissions standards. It uses mandrel-bent tubing, 16-gauge 409 stainless and OE-like flow dynamics with robust welds. Hardware is included to simplify installation and avoid reusing corroded factory parts.
