Vibrant 4-1 Merge Collector 1.625in Inlet I.D. Merge O.D. - 2.25in Outlet O.D. - 3.00in

Vibrant Performance is a well-known name for making solid exhaust parts, and this 4-1 merge collector is a great example of their work. If you're building a custom exhaust system, this piece is key for smoothly combining exhaust gases from four separate pipes into one. It's designed to help your engine breathe easier by creating a less restrictive path for exhaust flow, which can make a noticeable difference in performance.

This collector is built from 16-gauge 304 stainless steel, which is a strong material that holds up well against heat and corrosion. Every seam is TIG welded with a back purge, ensuring a clean and solid joint that won't leak. Vibrant makes these ready to weld right out of the box, so you can get straight to fitting it into your custom setup without a lot of extra prep work. The inside is hand-ported to ensure a smooth, unobstructed path for the exhaust gases, helping to maximize efficiency.

This collector has an inlet inner diameter of 1.625 inches and an outlet outer diameter of 3.00 inches, with a merge outer diameter of 2.25 inches. It's 8.25 inches long overall. Keep in mind that this part is not CARB approved and cannot be shipped to California.
