Product Description

The Vibrant Performance 10317 4-1 Stainless Steel Merge Collector is a precision exhaust component designed for custom header and exhaust systems. Its 4-into-1 design combines four primary tubes into a unified 4.00" merge outlet, helping to improve exhaust scavenging, reduce backpressure and support increased engine performance. Constructed from durable 304 stainless steel with TIG welds and hand-ported flow surfaces, this collector is built to handle high heat and demanding use.

With a 2.25" inlet slip-on diameter and a 4.50" transition cone outlet, the 10317 merge collector is ready for welding directly into custom exhaust and header applications. Ideal for builders and enthusiasts fabricating race headers or performance exhausts on naturally aspirated engines, it provides a smooth flow path and robust construction to support horsepower gains and efficient exhaust flow.
