PRODUCT LAYOUT  
 
The product has been designed for performance gains and for exhaust gas purification (only the Metal Catalyzer Version) and it's well balanced. The original factory stock layout has also been retained in this design for the best weight reduction results.
 
 
EXHAUST MANIFOLD
 
4-2-1 equal length layout designs
 
Uses a robust precise flange, and has the A/F Sensor boss.
 
The Lost-Wax casting process improves both precision and strength of the product.
And has the A/F Sensor boss.
 
By eliminating the first catalyst, we could achieve the best gas flow efficiency and further weight reductions.

METAL CATALYZER
 
The testing of several different types of cells, length & thickness, has led us to this 150cpsi cell design. It produces the best performance gains with the right smog emissions to comply with street regulations in Japan.
 
Boss for the A/F Sensor.
 
Meets the Japanese street legal emission standards with just a single catalyst.
