{"product_id":"60mm-stainless-steel-test-pipes","title":"60mm Stainless Steel Test Pipes","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.\n\nKey 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.\n\nThese 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.","brand":"Berk Technology","offers":[{"title":"Default Title","offer_id":52687118598456,"sku":"BT1401","price":216.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687889657.jpg?v=1784880524","url":"https:\/\/store.motormia.co\/products\/60mm-stainless-steel-test-pipes","provider":"MOTORMIA","version":"1.0","type":"link"}
