Infiniti G35 High Flow Catalytic Converters (HFCs)


Your luxury coupe or sedan deserves a luxury sound, and there's no arguing that the VQ35DE is one of the best sounding engines on the road. But it's been quite some time since the VQ35DE hit the market, and you'’re probably hungering for more power to keep you up to par with the G37s out on the track. So grab yourself a set of Motiv Concepts' High Flow Catalytic Converters, featuring 304 stainless steel RathGibson tube with our signature beautiful brushed finish. A pair of 200-cell count Magnaflow metallic substrate catalytic converters replace your restrictive factory ones, giving you performance gains without any of the headache.

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.
