Infiniti G37 High Flow Catalytic Converters (HFCs)


One of the easiest and safest ways to increase the performance of your vehicle is to replace your factory restrictive catalytic converters with high flowing ones. Motiv Concepts’ HFCs for the Infiniti G37 ensures you the best performance gains with the highest quality product possible. Sold in pairs, our HFCs are constructed with 100-percent stainless steel using 2.5-inch RathGibson tube. Our signature beautiful brushed finish gives it a look like none other on the market, while all new gaskets and hardware means you have everything you need to bolt-on and go.

Please note that all products are designed as OE replacement units. Fitment may vary if you are running aftermarket headers and/or an aftermarket exhaust system. Please contact a sales representative if you have any questions.

Motiv Concepts does its best to engineer its products to prevent the check engine light from illuminating. However, variables such as additional aftermarket parts may cause the check engine light to come on. We cannot guarantee that a check engine light will not trigger with the use of our product.

Includes all necessary hardware and gaskets to install.
