R35 GT-R Cobb SS 3.5" Catted Y-Pipe

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. 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 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 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. Power gains are similar between the catless and catted versions when using the stock GT-R turbos. Unleash the beast hidden within your Nissan GT-R with the new COBB 3.5"³ SS Y-Pipe and the COBB AccessPORT.
