4-1 Low Profile Header
$79.99 On sale
This header was designed to combine the exhaust gasses from each of the cylinders quickly while being cost effective. Our 4-1 low profile 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 1.5L-2.0L engines. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An extra added benefit is a more performance oriented exhaust sound.
