Most aftermarket downpipe back exhausts (that remove the second set of cats) save between 20 and 30lbs over the factory setup.

AE saves 24lbs
Britalman is about 30lbs

Others are similar. One of the things I like most about the HKS system and the AE system is that they use flanges to put together the pieces instead of slip joints.
