kill me for asking,
but....
headers vs. dutra duals (performance only!)

hoping Doug will come after this one...


also, how do i get my hands on some dutras (how many limbs will i have to sell on the black market?, or just how much will it cost me?)
thanks

As far as performance vs headers, I haven't used either one (yet - just got a set of dual Duals - thanks Doug!) but the duals will last longer than your car will - the tradeoff being a few pounds heavier compared to headers. Doug was running 12s on his car with Duals - that should be enough.

D. Duals perform as good as the "shortee" headers available these days, except they fit the car much better. As for performance gains, you can get 5 to 8% with the D.Duals compaired to 10-12% with a good set of long tube headers.
The cost for a machined front manifold is $225.00
