Description

The Stainless Bros 622-15276-5004 is a 3D-printed 4-to-1 merge collector designed for exhaust systems. It is constructed from SS316 stainless steel and features 3-inch OD primary inlets that merge into a 6-inch OD outlet. This collector is engineered for optimal exhaust efficiency, with an ideal 15° merge angle to support mid-range torque and top-end power gains.

This collector is designed to slip over 16-gauge SS304 tubing from Stainless Bros, ensuring a seamless fit-up with compatible tubing and bends. Its advanced 3D-printed design allows for complex internal geometries that surpass the capabilities of traditional billet collectors, resulting in smoother transitions and improved exhaust scavenging.
