In the meantime you could reduce the noise without losing all your gains by just swapping out your front pipe with the OEM one. The Cat will reduce the noise you are hearing without impeding the flow as much as other options. One other thing, make sure to plug the opening on the passenger side floor mat where the sound tube comes through. and flip your rear seats up.

What exhaust do you have?
The tune is going to have very little effect on volume of noise from an axle back exhaust.
You're better off running the stock cat-back with an aftermarket front pipe than the stock front pipe with an aftermarket cat-back. There's more power held back by the front pipe than the cat-back.
