Our 4-2-1 Tri-Y off-road racing headers are designed to allow the exhaust gasses to flow more freely from each cylinder and combine in a more efficient manner.
Tubing has been optimized for the 2.0L engine. This creates a reduction in cylinder backpressure and improved exhaust gas velocity.
These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
