I have a set of Kooks longtubes - 1-7/8" to 3" collectors, no EGR fitting. I also have a 3" pipe to 2.5" outlet off-road kooks xpipe if you're interested in that too. I just pulled both off my car last weekend to sell.
Neither part is CARB compliant for CA. Not sure if that matters to you or not.
$1100 shipped for headers
$350 shipped for midpipe
$1400 shipped for both
