Welcome.

Since you're naturally aspirated, there isn't much power to be gained from any exhaust work. That said, replacing the front manifold with a power log from ZZP will give modest gains. Replacing the down pipe with a 2.5 inch unit will also help. However, the power you'll get from these will be barely noticeable, and I wouldn't consider it worth the money or effort.

Anything behind the down pipe will not give you any power, just change the sound. However, since these 3800s sound so awful, I would recommend leaving the stock resonator in place and just changing out the mufflers in back. I have some Flowmaster 44s and the car isn't too loud inside, just a little deeper than stock. There are still some days when I wish I had left the exhaust alone, but overall I'd say it's a nice little upgrade in tone.
