The stock y-pipe with factory catalytic converters is a restrictive element in the GT-R's exhaust system. The Cobb 3.5in stainless steel Y-Pipe is offered in both catless and high-flow cat versions that reduce exhaust restriction and allow the GT-R to make more power with less effort. Both the catted and catless versions of the Cobb 3.5-inch SS Y-Pipe are constructed of 304 stainless steel and TIG welded. The stainless steel flex sections are internally-lined for added lifespan and smoother exhaust flow. Dual 3-inch downpipes feed into a 3.5-inch main pipe. The Y-pipe is designed as a direct factory replacement part.
The catted version of the Cobb 3.5-inch SS Y-Pipe uses custom-spun high-flow metal substrate catalytic converters that improve flow while protecting the environment by reducing emissions. The catless racing y-pipe deletes the catalytic converters entirely, further improving flow and allowing even more power. Speaking of power, at peak up to 28 HP and 46 ft/lb is gained! Increases of up to 50HP can be found in the midrange!
