2001. 3.0i??? Ohhh....nooooo! Sell it imediatelly and get 3.0d or at least 4.4i! 3.0i takes almost the same fuel like big engines and drives like a pregnant cow from 0-100! Even diesel goes better than 3.0i! Get fl diesel from 2004.chip it up and u will get about 250hp! Throw away catalysator! Cut off rear mufflers or just make mufflers empty and sound will be like 4.8is! For diesel it goes like a rocket from 0!

Here u can hear sound inside my office for short moment: https://youtu.be/PH_XXzIGJE4

At first u will need to take off the front any way (not sure) u have to take off 'metal plate' at front!
