Scavenger Series Y-Collector 3in x 4in Y300400

Exhaust scavenging efficiency directly impacts horsepower and throttle response—especially in naturally aspirated and forced-induction builds where header design matters. The Scavenger Series Y-Collector merges dual 3-inch primaries into a single 4-inch outlet, optimizing exhaust gas velocity and minimizing backpressure. If you're building a performance engine that demands precision exhaust tuning, this weld-on collector delivers the flow characteristics serious racers and engine builders expect.
