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 B18B-R with 1600cc engine but also the results of an extensive bench testing program. When building a B16B (1600cc) to 1800cc specifications we recommend the TODA B18C-R 96 spec header.
-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 → Ø48mm → 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. -Made of light weight stainless steel for both durability and looks -Flange manufactured by high precision machining center -The standard catalyst can be installed.
