A 3.0-inch normally closed, boost-open exhaust valve from Stainless Bros made in 304 stainless steel. This valve remains closed until boost pressure opens it, enabling boost-dependent exhaust flow control in 3.0-inch exhaust systems. It provides a robust, corrosion-resistant option for tunable exhaust architectures that need reliable boost-actuated operation.
