Flowmaster Y300400 Scavenger Exhaust YCollector 3.0"In/4.0" Out Aluminized

Flowmaster's unique, patented Scavenger Series Y-Collector is founded on the principle of Pulse Technology. The large D-Shaped ports in the collectors create a large surface area to help pull the exhaust pulses from the opposing connected cylinders. This creates a cleaner burn for the incoming fuel and air resulting in an increased and broader torque curve, putting more power in the rpm range. Flowmaster's Three Year limited warranty protects the Y-Pipes in non-race applications.
