These GESI Ceramic Core Catalytic Converters feature the same precious metal loading technology incorporated into the High Output metal core converters.

We use a large, high flowing ceramic honeycomb catalyst that performs significantly better than a typical stock covnerter and will put an end to most "Check Engine Light" problems.

The external shell features full stainless steel construction, including a mirror polished heat shield. Covered by a 5 year/50,000 mile warranty (on shell and tube ends only).
