Cobb Catless Y Pipe
COBB Tuning is pleased to announce the 3.5-inch Stainless Steel Y-Pipe for the Nissan GT-R. The stock y-pipe with factory catalytic converters is a restrictive element in the GT-Rs exhaust system. The COBB 3.5-inch SS 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.
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 is for off-road use only and deletes the catalytic converters entirely, further improving flow and allowing even more power.
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.
Unleash the beast hidden within your Nissan GT-R with the new COBB SS Y-Pipe and the COBB AccessPORT.
