Vibrant 4-1 SS Merge Collectors (1-7/8in Inlet Slipover ID 2-1/2in Merge Outlet OD) Single Unit

Starting with the precise fabrication and back-purged TIG welds, this Vibrant Performance 4-1 merge collector is built for serious exhaust work. It’s made from 16-gauge, T304 stainless steel tubing, which means it’s well-built and ready to handle the heat and corrosive elements exhaust systems face. The single slip design is particularly useful for naturally aspirated applications where you want to ensure a smooth transition of exhaust gases from the individual pipes into a single, larger pipe.

The slip-fit design on the inlets is made to work seamlessly with Vibrant Stainless Steel piping, making your fabrication process smoother. Inside the collector, the design is hand-ported to ensure there are no obstructions, promoting an unobstructed exhaust flow. This attention to detail helps improve the efficiency of your exhaust system. It’s ready to weld right out of the box, minimizing prep time for your project.

This collector has an inlet ID of 1-7/8 inches and a merge OD of 2-1/2 inches, with a 3-inch outlet OD. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's sold individually, so make sure you order the number you need for your custom exhaust build.
