i have some cad drawings of a header i had designed but never made for the protege.. Long runner 4-1 header. Pipes equalized early, so was easy to lengthen to bias the power lower, or shorten to bias it higher..
may consider giving the design to a manufacturer in exchange for a freebie
thats cool and all but some people want to go the non-turbo route and stay na and it would be nice to have a great quality header out there to make us power. A nice 4-1 or 4-2-1 longtube would be great and maybe it could have also an extra 02 bung on it so if you wanna run a wideband on it. Also it would be good for it to bolt up to ur exhaust as well. I would'nt know if you would make it that long or sell a pipe to bolt up the header to the exhaust.
Subbing i would be interested in a corksport header as well to compliment my corksport exhaust.
