  • TypeOther Appliances
  • Width17.52
  • Direct-fit for Cadillac, Chevy and GMC 4.3L V6 and 4.8L/5.3L V8 engines
  • 400-cell ceramic substrate optimises exhaust flow and emissions control
  • Front, left and right replacement locations covered in one unit
  • Complete hardware kit includes bolts, nuts, gaskets and clamp for installation

Direct-Fit Emissions Replacement

This catalytic converter is built to match the original equipment on Cadillac, Chevrolet and GMC models equipped with the 4.3L V6, 4.8L V8 or 5.3L V8 engines. It installs at the front, left or right position and includes the necessary gaskets, nuts and screws for a complete installation.

Upgrade From Failed Or Clogged Units

The converter replaces a damaged, clogged or stolen factory catalyst that triggers check-engine lights and fails emissions testing. The jump is worth it when the original unit no longer meets legal limits or restricts exhaust flow enough to reduce power and fuel economy.

Bolt-On Fitment Limits

Fitment is limited to the listed engine displacements and the front, left or right mounting locations. Vehicles with different engines, alternative exhaust routing or aftermarket headers will not align with the supplied flanges and hardware.

Questions about this item

Will the 17.52 in width fit the front left or right position on my 4.8L V8?

The 17.52 in width is designed for the front left or right replacement location on compatible 4.8L V8 engines.

Which hardware from the kit do I use first when bolting the converter to the 4.3L V6?

Start with the three M12×50 screws, matching M12 nuts and M12 gaskets for the primary flange connections.

When should I replace the wound gasket and the tapered gasket included in the package?

Replace both gaskets whenever the converter is removed or if an exhaust leak appears at the flange joints.
