unless ur runing huge boost the pipes will be fine i have nothing on mine and have run 18 psi before with just normal hose clamps, as long as theres a fair 20-30mm inside the hose it will be cool. as for the i/c mounted bov if ypoure going to do it make sure u stop swarf getting into the core coz its going to be hard to see whether its all out id steer clear myself, and just not have a bov never had any problems without one and makes a tough sound too.
