Vibrant 4-1 SS Merge Collectors (2-1/4in Inlet Slipover ID 3-1/2in Merge Outlet OD) Single Unit

Starting with the precise fabrication and TIG welded 304 stainless steel tubing, this Vibrant 4-1 merge collector is built for custom exhaust projects. It's designed with a single slip-over inlet that measures 2-1/4 inches ID, intended to fit snugly with Vibrant's own stainless steel piping. The collector then merges exhaust gases into a 3-1/2 inch OD merge section, leading to a 4-inch OD outlet, ideal for naturally aspirated applications where smooth flow is key to performance.

The 16-gauge, 304 stainless steel construction means this part is well-built to resist corrosion and handle the heat of exhaust gases. Inside the collector, the tubing is hand-ported to ensure there are no obstructions, helping exhaust gases exit the engine as efficiently as possible. This attention to detail in fabrication means it's ready to weld right out of the box, minimizing prep work for your custom exhaust build.

This merge collector is sold individually. Please note that this part is not CARB approved and cannot be shipped to California. It's a solid option for builders looking for a well-made component for their custom exhaust system.
