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

Starting with precise fabrication using 16-gauge T304 stainless steel tubing, this Vibrant 4-1 merge collector is built for custom exhaust projects. The slip-over inlet design is intended to connect with Vibrant's own stainless steel piping, making it a straightforward choice for builders using their system. This collector is specifically designed for naturally aspirated applications, where managing exhaust pulses efficiently can make a notable difference in performance.

The construction includes back-purged TIG welds at every seam, ensuring a strong and clean joint that resists leaks and corrosion. Inside the collector, the design is hand-ported to promote smooth, unobstructed exhaust flow, which helps reduce backpressure and can improve engine response. It's ready to weld right out of the box, minimizing prep time for your fabrication project.

This collector has a 2-inch inside diameter inlet that merges into a 3-inch outside diameter section, with a 3.5-inch outside diameter outlet. Remember that this part is not CARB approved and cannot be shipped to California. It's sold individually, so plan accordingly for your exhaust build.
