Y-Pipe (Street Version) Features: •Constructed out of 304 stainless steel tubing for strength and durability •True 2-to-1 mitered merge collector eliminates dead zone for improved flow •No modification to stock system or location for hassle-free installation •Mandrel-bent 2-1/2in. into 3in. piping transitions for better powe r •Incorporates dual high-flow 48-state-legal 400 cell catalytic converters for optimum flow Test Results •In testing; the y-pipe produced a max gain of+15 horsepower and+13 ft. lbs. of torque verified by our in house dyno (tested on 2003 Nissan 350Z V6-3.5L with stock exhaust manifold) High Fl ow Catalytic Converters: Dual 48-state-legal 400 CPSI catalytic converters are used for maximum flow. Massive Y-pipe: The unique 3-piece y-pipe is designed using a merge collector that utilizes a 2-1/2in. into 3in. transition for optimum flow while removing turbulences. True Merge Collector: Elimina tes dead space that can cause turbulence and hinder flow that formed collectors are prone to produce. Leak-Free Seal: High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface Combine with aFe s Twisted Steel Header (48-36103) For added performance Note: T his system is not currently CARB exempt and is not available for sale in California or for use on any vehicle registered with the California Department of Motor Vehicle. aFe headers and exhaust are engineered and manufactured in our Corona; California manufacturing facility.
