First start on my new to me car, I haven’t heard it in person before and I think it sounds sick. bnr s4, catless down pipe and stock exhaust I believe

The hose is the one I’m holding in the first pic and the grey connector next to it, can’t find where the grey connector goes and don’t see where the hose could go, thank you in advance

Was torquing down bell housing bolts and this snapped, I replaced the clutch on this car and someone else took the trans out and nothing is organized so I’m not 100% sure thats the bolt but I couldn’t see where else it went and it looks like it came from there. Is that in a spot where I can get it or would I be fine to just put it all back together and take it to a shop to have them fix it?
