Looking for the 5 pot Warble

[audi2009022]

I recently got the back box, centre muffler and pipes replaced(All ss). The centre muffler is straight through and the back is muffled but less than stock. I still can't hear the 5 cylinder warble I was hoping for. I don't want boy racer loud I just want to hear the engine a bit more. Was thinking of getting the cat changed to a more free flowing one. Will that give me the result I have described or do I need to do more. I have a 200 Turbo if that make much difference.

Thanks.
