Im going to get some DC headers but I don’t know which one is better for my 91 RS I asked around and I get different answers. So which one do you guys think is better 4-2-1 or 4-1?:shrug:
4-2-1, you would have to notch the cross member on your car to fit a 4-1 header. 4-2-1 usually have a wider power band any way.
P.S.- It’s HEADER, not headers our cars only have ONE.
well basicly it depends on what you want…4-1 header is for topend power and 4-2-1 is for lowend power…It also depends on what types of mod’s you currently have…If you are stock and only have intake and exhaust i would go with a 4-2-1 header…If you have a fully built motor and need the top end , then i would go with the 4-1…It all depends on where you need the power more…
