Product Description

The Vibrant Performance 10312 4-1 Stainless Merge Collector is a high-quality aftermarket exhaust component designed for custom header and exhaust fabrication. Made from robust 304 stainless steel and featuring precision TIG welds and hand-ported internal surfaces, this merge collector promotes smooth and efficient exhaust gas flow while minimizing turbulence and backpressure.

This universal collector features a 2.125" inlet slip-on design that easily integrates with compatible header primaries and a 3.5" merge outlet that transitions to a 4" outlet for downstream exhaust piping. Sold individually, the 10312 is ideal for performance engine builds, naturally aspirated applications, and custom exhaust systems where maximizing flow and horsepower potential is critical.
