4-2-1 D-SERIES HEADER DESIGN
The 4-2-1 configuration routes the four exhaust runners into two secondary paths before merging into the final collector.
This layout is a popular choice for street-oriented Honda D-Series builds where responsive exhaust flow and usable performance throughout the driving range are important.
Compared with the restrictive characteristics of many factory exhaust manifolds, the tubular stainless design provides a smoother, performance-oriented exhaust path.
