Product Description

The Vibrant Performance 10309 is a 4-into-1 slip-on merge collector built for fabricators and enthusiasts looking to maximize exhaust efficiency on naturally aspirated builds. Featuring full T304 stainless steel construction, precision TIG welds, and a hand-ported interior, this collector promotes smooth exhaust gas scavenging to help free up horsepower and improve throttle response across the RPM range.

Originally a technology reserved for professional racing, merge collectors are now widely used in custom street and track header builds. The slip-on design makes integration straightforward for header fabrication with 2" primary tubes, and the 3.5" merge outlet provides a clean transition to your downpipe or exhaust mid-section.
