The catless NISMO SS Y-Pipe is constructed of 304 stainless steel and TIG welded. The stainless steel flex sections are internally-lined for added lifespan and smoother exhaust flow. The Y-pipe is designed as a direct factory replacement part.
COBB would like to introduce its new and improved Nissan GT-R Downpipes with cast bellmouth! These high-flow, mandrel-bent, 304-stainless downpipes allow for better flow, faster turbo-spool and improved transient response. The COBB cast bellmouth downpipes are a direct OEM replacement and will bolt up to the stock exhaust system or aftermarket systems alike.
This beautiful exhaust system can be found on 1000+ HP GT-Rs across the world and no where will you see a complaint or more praise given to the competition.
