HR headers are mandrel bent using data acquired from a non-contact digitizing scanner for consistent production of every system. Equal length primary piping and cylinder matching ensures the best performance for your ride.
The merge collector on the 4-into-1 systems features a unique trapezoidal design that is proven to efficiently expedite gas flow by virtually eliminating turbulence. This design also improves ground clearance by allowing them to offset the top and bottom header piping.
The HR header eliminates the catalytic converter and are tuned for all out performance for racing applications. All necessary 02 sensor bungs are incorporated into each system.
Fits CRX, Civic and Integra K-Swap chassis.
