The Vibrant 4-1 stainless merge collector is built for naturally aspirated exhaust systems with mandrel-bent 304 stainless tubing and precision TIG welds. Hand-porting inside the collector smooths flow and reduces turbulence, and the unit is ready to weld directly into custom headers. Sold individually and covered by a two-year limited warranty for fabrication quality.
