{"product_id":"3-5-inch-cat-back-exhaust-pipe","title":"3.5-Inch Cat-Back Exhaust Pipe","description":"The Tomei Expreme Ti muffler is a premium, full titanium exhaust system engineered for the Nissan 400Z RZ34, as well as compatible Q50 and Q60 models with VR30DDTT or VQ37VHR engines. This Type-D model boasts a 3.5-inch (89.1mm) main pipe diameter and a 1.0mm thickness, constructed entirely from titanium for a significant weight reduction compared to OEM steel systems. Its oversized shell design is optimized to improve exhaust gas flow, potentially leading to better performance. The system includes all necessary installation hardware, such as bolts and nuts, along with Bolt Smooth Paste to prevent seizing under heat. The main silencer measures 6.0 inches (152mm) in diameter, with a sub-silencer at 4.7 inches (118.0mm), and the exit diameter is 4.5 inches (115.0mm). The entire assembly weighs only 14.4 lbs (6.5kg), a substantial decrease from OEM equivalents.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52873035874616,"sku":"TB6090-NS21D","price":1791.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-5-inch-cat-back-exhaust-pipe","provider":"MOTORMIA","version":"1.0","type":"link"}
