Pulse adrenaline air filter help

So I have a 2011 pulse adrenaline 125 and it's bog standard, decided to fit k&n style air filter to it, just slots onto the carb but now I have two rubber hoses and I don't know what to do, one of them is from the EGR valve (I think) and the other one is what I believe to be a breather from the crank case/gear case right under the air box, they both went into the air box and now I'm unsure what to do with these two hoses, I don't want to have EGR just for that bit more of performance boost and what I think is a breather I don't know what to do with, I'll upload pictures later on, I don't know whether just to put a bung in the end of each hose as they are both pushing air out, I don't want them to build up too much pressure and force the bung out, i would just like for people to help me confirm what these pipes are and if they are important or not and what I can do about them, all help is appreciated, and if you reply check back later as there will be pictures of it either on the main post or comments.

Personally I've just left them hanging. For the breather you can get a small cone filter like the K&N style one that you have.

My EGR valve has been removed on my Lexmoto adrenaline, blocked the hoses off that was left
