egr by pass noise

hi folks ,,,i did the egr by pass some time ago and felt diff at once , the original was a hell of a mess even at a mere 76k, now question is the braided pipe now fits to a blanked spigot thus any pressure to that cant go anywhere, now ive noticed the well known duck/ deflated balloon noise when i turn engine off, so if i disconnect that and cable tie it up but leave the pipe open will it do any harm or spew any thing out unwanted
cheers folks

but leave the pipe open will it do any harm
