Looking for a cost efficient way to improve the performance of your Nissan 350Z or Infiniti G35? Motiv Concepts’ High Flow Catalytic Converters help your VQ35DE breathe a lot easier thank to its 200-cell, metallic substrate cat. The full 100-percent 304 stainless steel construction features our signature beautiful brushed finish on mandrel-bent 2.5-inch RathGibson tube. Everything is manufactured in the United States, from the 3/8-inch thick stainless steel flanges to the included all-new gaskets and hardware.

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.
