Hey fellas. The results are comming in on the great header test. They tested about 10 headers on an almost stock ITR. The owner says: "The only thing on my car was a carsound cat, comptech ice box-tube, power steering belt removed, and a spoon oil cap"

Theres a thread on it in the Type R forum, but we are not type r guys. We are GSR and LS guys! Chat with your peers here!

All I can say is WOW...nice work. The OEM JDM 4-1 header did quite nicely.

 

Not bad for being DEAD LAST!

 

haha. The type-1 and DC JDM seem to be best bang for buck headers...i think i may order a DC JDM sometime soon.

My only gripe is that this test failed to show how the headers would do with more aggressive cams than type-r's, since most of the headers (Toda, Spoon, Jun, etc.) were designed to work best with wilder cams.

 

where's the results for the Edelbrock pro-flo headers? anyone know the gains for them with the optional 3" b-pipe?

 

whoa - comptech definitely kept up, even tho its a 4-2-1, why wouldnt people get that and maintain their low and mid? or at least thats what ill be doing

 

Anyone that wants to know the header results for a GSR go to http://www.dcsports.com/ght.html

they tested almost all of them except JDM
