    Sr20ve header options.

    Ssac type seem to be the default ones. cheap. smart people shorten the secondary's for good gains.

    so what do you chose? really comes down to your wallet. most guys with a stockish motor will be content with a 4-2-1 setup. more serious builds will gravitate towards a 4-1 setup, as they will shine at mid and higher rpms.

    for the 4-2-1 setup, you dont want long secondaries. if you look at the impuls or fuji's, and compare to the ssac's, you will see what i mean. the final choke point (around60mm)will be near the back of the motor, or your will be giving up some hp.

    for the 4-1 guys, your looking for 23-25 inch primarys with a 2 1/4 inch choke point. looks weird. works.

    good luck!

    dayum, some of those look nice.

    would custom be a possible option compared to the pricey-end of these off-the-shelf options?

    most of the 4-1 options are all custom ones. i dont know of anyone in australia who has made them. maybe worth a look if your keen but

    better add socal raceparts in here. they started with the first tr-y's, and now are making a few other designs as well. first ones a nice tri-y megaphone model, then the conventional tri-y





    they make a radical 4-1 that needs a 1/2 radiator to clear the primaries



    and their trialing a 4-2-1 which i think could be the next default srXXve header
