Buick LaCrosse Performance Exhaust - Magnaflow - Direct Fit Catalytic Converter - `05-`09 is a MagnaFlow direct-fit catalytic converter engineered for 2005–2009 Buick LaCrosse. It provides CARB-compliant emissions control with an OE-style fit so you can replace the factory unit without cutting or welding.
Constructed around a spun-body design with a single laser fusion weld, this converter replicates original equipment flow dynamics while reducing potential leak points. Mandrel-bent tubing and high-strength 16-gauge 409 stainless steel tubing offer corrosion resistance and long service life. OE-sized barbed hangers made from corrosion-resistant 410 stainless steel help minimize noise and vibration. Essential gaskets and hardware are included to help ensure a proper seal. This unit is designed to meet California Air Resources Board requirements; installation is permitted only if the vehicle’s Executive Order (EO) number and Engine Family Number (EFN) appear in this converter’s CARB Executive Order. While intended for 2005–2009 Buick LaCrosse, it is also compatible with certain GM applications where specified.
