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

Vibrant Performance is well-known for their high-quality exhaust fabrication components, and this 4-1 merge collector is a prime example. If you're building a custom exhaust system, especially for a naturally aspirated application where smooth flow is key, this collector is designed to help you achieve that. It takes exhaust gases from four separate pipes and smoothly combines them into a single outlet, which is crucial for maintaining engine performance.

This collector is made from 16-gauge, 304 stainless steel tubing, which is a solid choice for exhaust components because it resists corrosion and holds up well to heat. The inlets are precisely cut and the entire piece is TIG welded with back purging for strong, clean seams that won't leak. Vibrant even mentions that these collectors are ready to weld right out of the box, meaning less prep work for you. The slip-over design for the inlets is intended to fit well with Vibrant's own stainless steel piping, making it easier to integrate into your custom setup.

Because this is a fabrication part, it's sold individually, and you'll need to plan your system accordingly. It's important to note that this part is not CARB approved and cannot be shipped to California. If you're looking to build a performance exhaust system, this merge collector offers a well-made foundation for combining your exhaust runners.
