headers? mmw, megan, or dme?
the MMW header is the same as the weapon r 4-2-1, for an NA car a 4-2-1 header has more gains than a straight 4-1 since it creates even flow and backpressure. The only real downside you sill see for getting a Weapon r 4-2-1 header is they are backordered for months and they are alot more expensive.
Thats what i thought that the weapon-r header and MMW header are essentially the same thing.
