Actually, it is the opposite. A single filing spouse subjects all of the community property to the estate, and your interest in that property is not protected to the extent that you do not have an exemption for that part of the community property. For instance, if you have three cars, each worth $5,000, you and your wife would get the $5000 exemption for one car each. If you and your wife only had one $5000 car, you would lose your exemption for a vehicle since there is no vehicle.
As to your income, all of your income is imputed to your filing spouse for Means Test purposes, but it is not separately attachable per se.
