I spent $680 before tax on the entire exhaust including labor. I'm not sure of the exact weight loss, but it's a lot. Going from the stock heavy muffler and 2nd cats to a small single muffler with the pipes has got to be a lot for a mod like this.

This past weekend Josh and I discovered a small different between his 2000 S and my 2001 S. His 2nd cats have an O2 sensor after the cat, when mine did not. Mine only has an O2 sensor before the 1st cat, and then one right after it, all on the header. Everything I did to the exhaust was after all O2 sensors.
