We present exclusive meaurements of the pp→pnπ+ and pp→ppπO reactions at 1.25 GeV, 2.2 GeV and 3.5 GeV and of the pp→ppπ+π- reaction at 1.25 GeV with the High Acceptance Di-Electron Spectrometer at GSI. Total and differential cross-sections for the one-pion production channels are analyzed with the resonance model to extract the differential baryonic resonance contributions. A comparison of the two-pion production channels to effective lagrangian model predictions is on-going. The two-pion invariant mass and opening angle distributions show sensitivity to the double Δ(1232) and N(1440) → Δπ decays.
