Ssac type seem to be the default ones. cheap. smart people shorten the secondary's for good gains.
896
fuji's. feedback of a great sounding header
897
impul.
898
p12 20v. good gains up top over ssac. heavy. can run into fan trouble with this one.
899
tri-y ebay. potential fitment issues. proven gains over ssac.

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
