Vibrant 4-1 SS Merge Collectors (2-1/8in Inlet Slipover ID 3-1/2in Merge Outlet OD) Single Unit

If you're building a custom exhaust system for a naturally aspirated engine, a well-fabricated merge collector is key to getting smooth, unobstructed exhaust flow. This 4-1 merge collector from Vibrant Performance is designed to help you achieve that. It takes the exhaust gases from four separate pipes and smoothly combines them into a single outlet, which is crucial for maximizing performance in non-turbo applications.

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. Vibrant uses precise fabrication and back-purged TIG welds on all seams, meaning you get a strong, clean joint that won't leak. The inlet ports are designed to slip over standard Vibrant stainless steel piping, making it easier to integrate into your custom setup. It also features hand-porting inside the collector to further smooth the transition of exhaust gases.

This collector is ready to weld right out of the box with minimal prep work needed. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's sold individually, so make sure you order the correct number for your application.
