Greg:
Those 2 comparisons don't surprise me. If you look at the original chambered exhuast (or even the original dual exhuast) from a performance stand point, it will make you sick. But, I am a true blue purist, and I would like to keep our Camaro as stock as possible. BUT, now that I'm in the 12s on the stock exhaust...a few tenths would be nice...
