When the factory catalytic converter on 2008-2012 Isuzu i-290, Chevrolet Colorado, GMC Canyon 2.9L fails or trips a P0420-series code, the MagnaFlow 5582378 provides a California Grade CARB-compliant direct-fit replacement that restores exhaust flow and emissions compliance without custom fabrication.

MagnaFlow 5582378 Installation Notes:

• Integrated exhaust manifold and catalytic converter design replaces both components in a single direct-fit unit, eliminating a separate manifold-to-converter joint.
• Constructed of stainless steel with a ceramic substrate for durability and consistent catalytic performance.
• Flange inlet and outlet connections replicate the factory mounting configuration for a bolt-in installation.
• Overall length of 18.5 in. matches the factory converter footprint.

This converter carries CARB Executive Order D-193-199 and is certified for sale and installation in California.

Emissions Note:

This part is legal for sale and use on Emissions Controlled Vehicles, in all 50 states, when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number.
