Magnaflow 07-08 Chevrolet Silverado 1500 4.3L Direct Fit Converter

A failed catalytic converter on a 2007-2009 Silverado 1500 or Sierra 1500 means a check engine light and a failed emissions test. MagnaFlow's direct-fit converter part 5451194 is the CARB-compliant replacement, legal in all 50 states including California and other CARB-regulated states.

MagnaFlow builds this converter with 16 ga. 409 stainless steel tubing and mandrel bends that replicate the factory exhaust routing. The spun body design with a single laser fusion weld reduces the potential for exhaust leaks, and the stamped collector is shaped for consistent flow. The 308 stainless steel MIG welds handle structural joints throughout. A Torca AccuSeal clamp, crush ring gasket, and donut gasket are all included in the box, so you are not reusing corroded factory hardware during installation.

Beyond the Silverado and Sierra 1500, MagnaFlow lists fitment for the 2008-2009 Chevrolet Tahoe, 2008-2009 GMC Yukon, and 2009 Cadillac Escalade. No cutting or welding is needed -- this is a direct bolt-in. Installation is permitted only when the vehicle's Executive Order number and Engine Family Number match this converter's CARB Executive Order.
