Vibrant 4-1 SS Merge Collectors (1-7/8in Inlet Slipover ID 3in Merge Outlet OD) - Sold Individually

Starting with precise cut mandrel bent 304 stainless steel tubing, this Vibrant 4-1 merge collector is built for performance exhaust fabrication. It features a single slip design, making it a good choice for naturally aspirated applications where smooth, unobstructed exhaust flow is key to making power. The expanded inlets are made to fit perfectly with Vibrant Stainless Steel piping, simplifying your fabrication process.

This collector is constructed from 16-gauge, T304 stainless steel, known for its strength and resistance to corrosion, and all seams are back-purged and TIG welded for a solid, leak-free connection. The hand-ported inside of the collector helps ensure exhaust gases transition smoothly from the multiple inlets to the single outlet, minimizing turbulence. It's ready to weld right out of the box with minimal prep work needed, saving you time in the shop.

This part is sold individually and is not CARB approved, meaning it cannot be shipped to California. It's designed for custom exhaust builds where precise fitment and smooth flow are critical.
