We focus on exclusive production of neutral technipion $\tilde \pi^0$ in $pp$collisions at the LHC, i.e. on $p p \to p p \tilde \pi^0$ reaction. Thedependence of the cross section on parameters of recently proposed vector-likeTechnicolor model is studied. Characteristic features of the differentialdistributions are discussed. For not too large technipion masses the diphotondecay channel has the dominant branching fraction. This is also the main reasonfor an enhanced production of neutral technipions in $\gamma\gamma$-fusionreaction. We discuss potential backgrounds of the QCD and QED origin to the $pp \to p p (\tilde{\pi}^0 \to \gamma \gamma)$ process at large invariant$\gamma\gamma$ masses. We conclude that compared to inclusive case thesignal-to-background ratio in the considered exclusive reaction is varyfavorable which thereby could serve as a good probe for Technicolor dynamicssearches at the LHC.
