Both the catted and Race 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 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.
