I said this already but the reason Eric gs dyno DID NOT PROVE the merit of the SHM headers is because it was looking at a custom chip. With the SHM headers/y-pipe/custom catback other mods he was at 165 HP and 160 lb/ft. Plenty of people have made that with no mods or just a Y-pipe. The custom burn chip put him at 176/171, very nice but THE CUSTM BURN CHIP MAY HAVE BOOSTED HIM THAT MUCH WITHOUT THE HEADERS - we just do not know. No body else has done a dyno tuned chip on this forum to know, but I suspect with just the Y-pipe/catback intake a dyno burned chip would provide nice gains. You simply cannot draw any conclusion about the headers (maybe they are worth the bux, maybe not).
