Show original supplier description
It features mandrel-bent piping for optimal exhaust flow, coupled with TIG-welded CNC flanges for a precise fit. Anti-reversion chambers and integrated flex pipes are included to further enhance performance and reduce exhaust turbulence. This downpipe comes equipped with a 3-inch EPA-approved catalytic converter, though the brand may vary. It is designed with two O2 sensor locations, including a built-in O2 sensor extender for convenient integration with existing sensor setups. The catalytic converter will require welding onto the Y-pipe for installation. This product is intended for use on uncontrolled vehicles and for off-country use only. It is explicitly stated that it should never be used on any pollution-controlled motor vehicle. To complete a purchase, customers must set up an account and fill out a specific form; orders will not ship until this form is received. Installation instructions are not provided; referring to a shop or factory manual is recommended. This downpipe is compatible with the Nissan 350Z models from 2003-2006 and Infinity G35 models from 2003-2006.
