I weighed mine shortly after I got it. Fuel light was on, no tools. The didital scale it was on kept blinking between 390 and 400, so it's safe to say it weighed a little under 400. I am very happy with that. I have the CF FMF's on mine. Other than the exhaust, the SD is pretty much what it is. SAS system is maybe a pound, but is that going to be noticeable?
*New years resolution: finally drop a few pounds. The first thing I did was quit drinking soft drinks and sweet tea. That alone saved me aprox 400 calories a day. But the real benifit is, now that I am drinking water, my appetite for chips, cookies, candy, and other junk has pretty much gone away. it's been only 10 days, but I can already tell that my work pants are getting a bit looser.
