Vibrant Performance® 2466 - 304 SS 4 into 1 Merge Collector for T4 Divided Flange

All Vibrant Performance Merge Collectors feature complete T304 Stainless Steel construction, precise fabrication, top quality TIG welds at every seam and hand porting inside the collector for smooth, unobstructed exhaust flow.

In order to maximize torque and horsepower, a vehicle’s header and exhaust system must optimize exhaust gas velocity. Anything that reduces exhaust gas speed will negatively impact performance. A header featuring a conventional collector generally suffers from a significant reduction in exhaust gas velocity at the transition from the primaries into the collector. This drop in velocity will decrease volumetric efficiency and reduce scavenging ability. This is key because optimizing volumetric efficiency of an exhaust system allows for improved air/fuel mixture in the combustion chamber, thereby improving an engine’s horsepower and torque production potential. A properly fabricated Merge Collector significantly minimizes the exhaust gas velocity loss at the transition from primary tubes to the collector and as a result, the volumetric efficiency potential of an exhaust system is significantly improved. To get maximum benefit from Merge Collectors, dyno testing is crucial to ensure your set up is able to realize its full potential.
