By far comptech will eat any of those headers listed, if you can try to find a comptech used in good shape, thats what i did for my 98 ex, i got mine for 150 and when i sold my car for my si, a guy offered me 285. resale value is great on comptech products . i have a comptech stainless 4-2-1 on my 00 si and my dyno with joe schmoes intake, and apexi ws was 141.7 whp 100.lbs of tq, with header 149.2 whp 104.7 lbs of tq. that is untuned ( car runs extra rich) with a busted clutch. not only is performance amazing but the tig welds are awesome and fitament doesnt get better. just my 2 cents take it for what its worth and have fun building ur car.
