Vibrant 4-1 Merge Collector 2.50in Inlet I.D. Merge O.D. - 4.00in Outlet O.D. - 4.50in

This Vibrant Performance 4-1 merge collector is built from 16-gauge, 304 stainless steel, a solid choice for exhaust fabrication projects. The precise fabrication and back-purged TIG welds at every seam mean you're getting a well-built part that’s ready to go straight out of the box with minimal prep work. Its design aims for smooth, unobstructed exhaust flow, which can help improve performance in custom exhaust systems.

With a 2.50-inch inlet inner diameter and a 4.50-inch outlet outer diameter, this collector is designed to efficiently combine exhaust gases from four primary tubes into a single outlet. The hand-ported interior further ensures that exhaust gases transition smoothly, reducing turbulence and back pressure. This attention to detail in construction is key for anyone building a custom exhaust where flow dynamics are critical.

This collector is sold individually and comes with a 2-year limited warranty from Vibrant. Please note that this part is not CARB approved and cannot be shipped to California.
