Switching from an  exhaust manifold to exhaust header scion (also known as extractors in Australia) will  header optimize the exhaust gas flow speed  and in turn increase the high-end power of the engine speed and in  turn increase the high-end power of the engine. This is done by using    individual pipe for each exhaust  port that has smoother bends, decreasing airflow resistance, as well as a calculated pipe diameter to obtain a good scavenging effect for the specific engine capacity. The pipes then merge together into a collector and then flow into a larger pipe (down pipe), just before the catalytic converter xb header .

• n 1987, American Honda commissioned DC xb Sports to develop a header for SCCA-prepped CRXs. What culminated was our first 4-into-1 header design, great for scion .And it was so well received that Honda requested headers for other applications. That system (HHC5002) is the one that stared it all. DC Sports 4-into-1 header xb are available in T-304-stainless steel, and in mild steel with a proprietary temperature- and corrosion-resistant xb headers ceramic coating. Once our mild-steel systems are completed in manufacturing, they are subjected to a thermal degrease and a xb header preliminary sandblast to prepare the header surface for coating adhesion.  K-Series Bifurcation: The DC Sports bifurcation is found in our K-Series header. In the case of Honda's K-motor, adjacent firing pulses from header pipes in close proximity can xb header cause contamination in the xb cylinder chambers and negatively affect performance. xb The bifurcated design in our K-Series collector prevents this by helping separate the firing pulses for cleaner burning cylinders and more power xb headers . Trapezoidal Merge xb Collector: Our merge collector on our 4-into-1 systems features a unique trapezoidal design that is xb proven to efficiently expedite gas flow by virtually eliminating turbulence. This design also improves ground clearance by allowing us to offset the top and bottom header piping.Dyno tuned and tested against the competition for maximum xbperformance CAD-rendered, race-inspired 4-into-1 xb  design emphasizes top-end power for road racing applications 50 state legal or pending legality Available in 100% 304 brushed or polished stainless steel (including flanges), or mild steel with ceramic coating CNC mandrel bends with robotically-welded fittings deliver perfect fit xb header  .
