blaa not really true. if you look at DTR smp and other companies like that they all have 4-2-1. its all about which header you get not the style

this is the most common answer but is not necessarily true....... i've seen dyno charts where the dc sports 4-1 made more power across all rpms than the dc sports 4-2-1..........
