In order to get the best performance, engine power, efficiency, this exclusive exhaust manifold design takes into consideration not only the special characteristics of VTEC B18C-R engine but also the results of an extensive bench testing program.

Our 4-2-1 type now available as Ver.2 strengthened
The part of a racing look is removed by the strong request from the competition customers. It became simple structure.

The reinforcement plate is added
The reinforcement plates are added to each racing junction and a head plate to each pipe exit.

A bench test (Equal length 4-2-1 + Taper) design
Ø45mm → Ø50mm → Ø55mm → Taper → Ø60mm
*Taper design is adopted from feedback from both racing and the bench testing.

Racing high flow junctions design
Each section of the manifold has optimized pipe lengths, diameters and angles as well as high flow junctions.
