COBB Tuning's 3.5inch Stainless Steel Y-Pipe for the Nissan GT-R is an essential upgrade to the R35 GT-R. The stock y-pipe with factory catalytic converters is a fairly restrictive element in the GT-R's exhaust system. The COBB 3.5inch 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 3.5inch SS Y-Pipe uses custom-spun high-flow metal substrate catalytic converters that improve flow while protecting the environment by reducing emissions. The off-road racing y-pipe deletes the catalytic converters entirely, further improving flow and allowing even more power.

Both the catted and catless versions of the COBB 3.5inch SS Y-Pipe are 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 3inch downpipes feed into a 3.5inch main pipe. Designed as a direct factory replacement part.

At peak power, 28 HP and 46 ft/lb is gained with the catless y-pipe over a Stage 1 AccessPort GT-R tune alone. Gains of up to 50HP can be found in the midrange.
