I made a request from "headers by ed" for my tr4. 2289cc,10:1 comp, 40mm dellortos, 6000rpm max, 290 cam, through mufflers, for "flexibility" instead of max hp.
answer: 36"lg,1.5" primaries-equal length +- 1/16".
Collector per his design 6"lg outlet 2 1/2"-see his web site for collectors (his are 5" lg.)he says this design is important.
2 1/2" muffler(s).
make connecting pipe from header to muffler 2 1/2" but removeable to try smaller pipes (i think 2 1/2" may be too large- 2 1/4" may turn out to be better)
he says that headers with mufflers are NOT the same as headers without mufflers. this guy has been designing & building headers for 40 yrs whith a lot of dyno feedback. that's a lot of headers. i'll give it a go. now to make an accurate jig for my chop saw. /ubbthreads/images/graemlins/yesnod.gif /ubbthreads/images/graemlins/square.gif
