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

Starting with precise fabrication, this Vibrant 4-1 merge collector is built from 16-gauge, T304 stainless steel tubing. The slip-over design is ideal for naturally aspirated applications, helping to create a smooth, unobstructed path for exhaust gases as they combine from the multiple inlets into a single outlet. This collector is ready to weld right out of the box, with back-purged TIG welds at every seam to ensure a solid, leak-free joint.

The expanded inlets are designed to fit seamlessly with Vibrant stainless steel piping, making integration into your custom exhaust system straightforward. Hand porting inside the collector further refines the exhaust flow, minimizing turbulence and maximizing efficiency. This well-built component is a key piece for anyone fabricating a custom exhaust system where smooth flow and durable construction are important.

This merge collector is sold individually. Please note that this part is not CARB approved and cannot be shipped to California. It is recommended to check manufacturer fitment data for compatibility with your specific piping and vehicle setup.
