If the exhaust system terminates under the vehicle and not past the bodywork at least a few inches, exhaust smells can infiltrate the cabin through even the smallest cracks and crevices. Even a loose clamp can be enough.
Many times the smell can come in from the firewall, so be sure there are no header/manifold/exhaust pipe leaks under the hood and the firewall is sealed well.
