Lacking a secondary air system hardly makes that kind of difference. All the vacuum tubes and switches are still there for the EGR and evap. In fact, the AIR system (other than being physically in the way) is pretty much non intrusive. It helps the catalyst do its job, and in theory makes the exhaust system last longer - by raising the exhaust temperature and preventing condensation.
Of course, the pumps have a bad habit of falling into disrepair and seizing up. Plus they're kind of just extra crap in the way (as previously mentioned).
