Show original supplier description
The Berk Technology test pipes are a performance exhaust upgrade designed for the Nissan 350Z and Infiniti G35 models equipped with the VQ35DE engine. These test pipes replace the restrictive factory catalytic converters, utilizing 60mm, mandrel-bent 304 stainless steel tubing to significantly improve exhaust flow and velocity. The construction includes TIG-welded flanges for durability and resistance to cracking. Key features of these test pipes include integrated mini-cat spacers, designed to reduce the occurrence of check engine lights (CEL) in approximately 95% of normal operating conditions. Additionally, each pipe is equipped with an extra O2 bung, providing a precise location for wide-band sensor installation, which is beneficial for custom tuning. The package includes leak-free soft crush graphite collector gaskets, as well as all necessary hardware for installation, with an average installation time of about one hour. These test pipes are intended strictly for off-road or race-only use and are not legal for installation on pollution-controlled vehicles intended for highway use. Users are advised to verify local regulations regarding emissions compliance before installation. The product is compatible with 2003-2006 Nissan 350Z (Coupe, Convertible Roadster) and 2003-2007 Infiniti G35 (Coupe, Sedan RWD/AWD) models with the VQ35DE engine. For VQ35HR and VQ37HR applications, part number BT1407 is required.
