3-Inch Stainless Steel Downpipe

The ISR Performance 3" Stainless Steel Downpipe is a performance upgrade engineered to enhance exhaust flow for competition vehicles. Constructed from durable 304 stainless steel, this downpipe features a 3-inch diameter and a flex section to accommodate engine movement. Designed as a direct bolt-on component, it connects seamlessly to the factory catalytic converter or an aftermarket test pipe. The package includes all required gaskets and hardware for a straightforward installation process. This downpipe is explicitly intended for use in competition vehicles that will not be registered for street use. Its design focuses on maximizing exhaust efficiency, providing a freer-flowing path for exhaust gases out of the engine.
