Show original supplier description

The Flashark Y-Pipe Exhaust Downpipe/Test Pipes are designed to boost performance for the 2003-2009 Nissan 350Z and the 2005, 2007 Infiniti G35 with 3.5L engines. Crafted from premium 16-gauge T-304 stainless steel, this component features a mirror polish finish, computerized mandrel-bends, and TIG-welded joints to prevent cracking and wear. The CNC-machined flanges are chrome-plated for added corrosion resistance, ensuring superior strength and longevity. This results in an estimated increase of 10-15 HP and 5-10 ft-lbs of torque, leading to quicker throttle response and an overall more exhilarating driving experience. It also contributes to a deeper, more aggressive exhaust note. The package includes the Y-pipe, gaskets, screws, and nuts. Flashark offers a permanent warranty on this product, underscoring their commitment to quality and customer satisfaction. Please note that this Y-Pipe Downpipe may reduce the effectiveness of stock catalytic converters, and users should verify compliance with local emissions regulations before installation.
