Description
Replace a failing catalytic converter with a direct-fit, OEM-grade MagnaFlow unit engineered to restore emissions compliance and maintain drivability on 2006–2008 BMW Z4 3.0L applications. This Federal/EPA compliant converter uses highly corrosion-resistant stainless steel construction and mandrel-bent tubing to preserve exhaust flow while duplicating the OE spun body geometry for reliable fit and function. The compact, low-mass design with a single laser fusion weld reduces leak potential and improves thermal efficiency, and the kit arrives with gaskets and installation hardware so you can complete the bolt-on replacement without cutting or welding.
