Every wonder why factory cats are $1200 and most aftermarket are $200? The materials required for catalytic converters is expensive. Period. You cannot build a proper cat for a forced induction application for that price. the materials are too expensive.

We recommend using the OE Cats or just cat delete depending on local laws.

I just upgraded to GM NPP Dual Mode exhaust system. Hope that still qualifies for your IPF kit....
