Can I go with out my intake flex pipe
 

I use a K&N drop in and would like to remove my flex pipe just dont know if that would be ill advised

if you mean the part in the bumper area, the vfad, hen yes you can remove that. remember to cap off the vaccum source

I dident think it would matter if I did but I did wounder about that vacu line on the side
