Is this the thing you need to be able to eliminate your secondary air pump?

I'm curious, as the air pump is an emmisions piece that weights about 5lbs, that just pumps air into the primary cats (which I've eliminated with the euro headers). Apparently you'll throw a code without it, so I'll do it with my next upgrade/tune
EDIT: see page 3 for install of blocking plate. no codes thrown. 4.25 lbs saved
