You wont get more power but the exh note can be changed in many ways.

I disagree. You will gain a few kw from cat back exhaust if increase diameter of pipe. The biggest gains are from headers and high flow cats. For a start I would go cat back and remove secondary cats. This will yield a small kw gain. I use to drive a FBO 350 that was dynometered before and after so it does help with more kw.
