    Default headers choice

    hey all

    im looking at getting some headers for my 7AGE 20v Silvertop ..

    anyone have any suggestions in which i should go
    4-2-1 = low-mid power range
    4-1 = mid-high power range

    it is basically a daily street car so i was thinking of going for a 4-2-1

    anyone have any experiences and feel and great differences ??

    toda quote that with a stock 20v engine they gained 3% in the top end with their 4-1 design but lost a massive 15% power in the mid in comparasin to their long primaries

    4-2-1 with long primaries, look for decent bend off the flanges too. The only decent pipes I have seen are toda and p-craft
