Tode had one fabricated by some dude in Balcatta if I remember correctly?
Its all on NASIOC joesack, and the ported stock headers with aftermarket cross pipe, actually came in 2nd on the test they did with ALL headers. The best headers were the Perrin items, but these require the twinscroll sump as the bottom half of the headers is the same as the twin scroll units apparently. So going by this, you may actually be better off reverting back to modified stock headers?
Also have a read up on Rexnet regarding aftermarket headers vs. modded stockers. A guy tested them against a new set of Tomei unequal length headers - long story short, once the headers were fitted, E.Ts and terminal speeds dropped... once the modded stockers went back on, he gained more power everywhere.... weird?
Didnt sean do this to josh's car aka abuse? Modded headers etc?
Sounds like a good idea though....not many people have done it, and seems to be working in Tode's case so why not eh?
