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-R's
exhaust system. The COBB 3.5-inch SS Y-Pipe is offered in ahigh-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.
The catted version 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 following dyno chart compares a stock un-tuned Nissan GT-R, a stock
Nissan GT-R with an AccessPORT Stage 1 tune, and a Nissan GT-R with the 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.
COBB 3.5” SS Y-Pipe:
• Large gains in HP & TQ
• 304 stainless throughout
• TIG welded
• Direct replacement for OEM
• Custom spun metal subtrate cats or catless options
• Similar power gains between catted and catless options using stock turbos
