So it breaks down to:

Race mufflers 9.6 each, sport 11.2 each: 19.2 - 22.4
OEM is 22 lbs each: 44
-24.8 to -21.6

X-Pipe weighs 11 lbs.
Stock weighs 15 lbs
- 4

s-pipe (9lbs) + 100 cell cats (7lbs): 16 lbs
stock US is 19 lbs
- 3

Adding that all together we get 28.6 to 31.8 lbs weight savings.

Might have to remove 2 lbs or so for the race clamps, as they're 0.4 lbs each. So 30 lbs might be a reasonably close estimate.
