2.5-Inch Stainless Steel Exhaust Y-Pipe

The ISR Performance Y-pipe is constructed from 2.5-inch stainless steel piping, designed to connect catalytic converter flanges to a high-performance velocity merge. This Y-pipe then transitions to 3-inch stainless steel piping leading to the rear exhaust flange. It incorporates bellowed flex sections to manage exhaust system movement and an integrated dimpled gusset plate for enhanced structural integrity. This Y-pipe aims to optimize exhaust tone, maintain good ground clearance, and improve performance at an accessible price point. It is specifically designed for the Nissan Z33 350z (2003-2009) and the Infiniti G35 (Non-AWD / Non-X Models). It is not compatible with the AWD Infiniti G35X; owners of that model should use part number IS-Z34-Y. If you are unsure about your G35 variant, it is recommended to contact the seller before purchasing. Included in the box are the exhaust Y-pipe, two 2.5-inch 2-bolt exhaust gaskets, one 3-inch 2-bolt exhaust gasket, six nuts, and six bolts. The product is intended for racing vehicles and is legal in California only for such applications.
