I've read all the stuff about less back pressure at higher RPMs. I plan on maintening those lower RPMs for lean burn and FE. Seems to me trading it off for a stock would be the thing to do??? I'm confused lol
I still don't have enough info for the pipe calculator. Dont know where to find valve opening BTDC or closing ATDC or duration...
Thanks!

sivx,
your civic new produced max 92hp at 6000 rpm.
you need a single pipe in the 1 1/2 diameter
based on the chart above.
