COBB Tuning is pleased to announce the 3.5" Stainless Steel Y-Pipe for the Nissan GT-R. The stock y-pipe with factory catalytic converters is a fairly restrictive element in the GT-R's exhaust system. The COBB 3.5" SS Y-Pipe offers two options that reduce this restriction and allow the GT-R to make more power with less effort; one with catalytic converters and one without.
The catted version of the COBB 3.5" SS Y-Pipe uses custom-spun high-flow metal substrate catalytic converters that improve flow while protecting the environment by reducing emissions.
This COBB 3.5" SS Y-Pipe is fully 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" downpipes feed into a 3.5" main pipe. Designed as a direct factory replacement part.
The following dyno chart compares a stock untuned Nissan GT-R, a stock Nissan GT-R with an AccessPORT Stage 1 tune, and a Nissan GT-R with the catless Y-Pipe and AccessPORT tune. At peak power, 28 HP and 46 ft/lb is gained with the catless y-pipe over Stage 1. Gains of up to 50HP can be found in the midrange.
Unleash the beast hidden within your Nissan GT-R with the new COBB 3.5" SS Y-Pipe and the COBB AccessPORT.
