FIT 06-11 CIVIC SI FG2/FA5 K20 STAINLESS 1.75″ID 1PC FLEX TRI-Y EXHAUST HEADER
* Features
Description:
This exhaust manifold for the 2006-2011 Honda Civic SI 4 Cylinder Engine were designed to combine the exhaust gasses from
each of the cylinders quickly with a manifold that was cost effective to produce. 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.
