Question for those with X pipe
 

Tomorrow i will have my tech made an X pipe for my 4.4. He charges me 95 euros to make an X pipe plus install.
Would like to ask few questions about the inside noise before/after X pipe install. Does it make a noticeble difference from inside the cabin with windows up after install?
Does the exhaust has a different tone after the X install, or you just hear a slight louder sound from the engine area bay?

Just want to make sure I´m making the right decision. Thanks in advance.
