Headers

Recommended Headers

As usually the stock parts were not designed with you, the performance enthusiast in mind. Most stock Acura headers come with a crude, cast iron, log-type manifold. These types although well designed are detrimental to power production. Once again mandrel bends are preferred for increased performance. They create more power through resonance tuning; a technology which improves the "scavenging effect". The "scavenging effect" is the vacuum created behind the exhaust charge, which helps clear out more exhaust-fumes during the overlap period when both valves are open.

Tri-Y Headers (4-2-1)	4-1 Headers
Tri-Y headers are the best design for street cars. They are more forgiving to camshaft design and other tuning factors, which you have little control over. Tri-Y headers promote a wide powerband, but at the cost of a lower peak power output. This is a better choice for daily driving.	The four into one header design is best suited for race cars, because they create a higher peak power output.
