I am already craving another one
I have a CP-E motormount sitting in my garage waiting to be installed, and I am also supposed to get a custom exhaust built from my secret hookup too.
The catback on your car is very good as is. If you want more sound remove one or both the resonators in the catback. A shop will cut them out and weld in straight pipe. For more performance, remove the secondary cat and replace it with straight pipe or buy a test pipe. For more power still replace the down pipe.
