I saved a bunch of weight when I got rid of all the rust and old grease from my front end. Ti cam bolts or not, clean parts weigh less.
Seriously, on my car, there was decades of dirt built up in the little shelf under the control arm mounts. It was a pain to get it all out of there. Probably good for several ounces.
On a related note, stock UCAs are lighter than fancy bling aftermarket tubing types.
