Vibrant 4-1 Merge Collector (1.625in Inlet I.D. Merge O.D. - 2.00in Outlet O.D. - 2.50in) Single

If you're building a custom exhaust system, a well-made merge collector is key to getting your exhaust gases to flow smoothly from multiple pipes into one. This Vibrant 4-1 merge collector is designed to help you achieve that, whether you're working on a header project or modifying an existing exhaust setup. It takes the exhaust from four separate pipes and merges them into a single outlet, helping to improve exhaust scavenging and potentially boost performance.

This collector is made from 16-gauge T304 stainless steel, which is a solid choice for exhaust components because it resists corrosion and holds up well to heat. The fabrication is precise, and all the seams are TIG welded with back purging, a technique that helps ensure a strong, clean weld on the inside as well as the outside. The inside of the collector is also hand-ported to create a smooth, unobstructed path for the exhaust gases, which can help prevent turbulence and improve flow efficiency. It's ready to weld right out of the box, so you can get to work on your custom fabrication project with minimal prep.

This collector has an inlet inner diameter of 1.625 inches and an outlet outer diameter of 2.50 inches, with a merge outer diameter of 2.00 inches. It's 8.25 inches long overall. Keep in mind that this part is not CARB approved and cannot be shipped to California.
