Agreed. Exhaust should be one of your first mods, as the stock system is atrocious.

what I would do is get a custom exhaust made. get like a 3" exhaust all the way from your headers!
Dual 3" from the manifolds/headers back would be excessive for his setup.
Curtis, if/when you do want to have a custom exhaust made for your car, I highly recommend House Springs Discount Muffler (south of St. Louis, in House Springs, just off Hwy 30). They have a guy that comes in on Saturdays to do custom work. I can't think of his name at the moment, but he owns a 89 XR7, and he absolutely loves these cars. He has done a few exhaust setups for me.

what is the size of your exhaust if 3" is excessive?
For 300rwhp all you need is to replace your downtubes and resonator. The back half of the exhaust will be ok. Use 2.25" pipes. All together it shouldn't cost more than $400-500 installed with cats.
The setup in those pictures is dual 3", but that car doesn't exactly have a 3.8L SC engine in it anymore. That setup was actually overkill for the 4.6L DOHC V8 in its semi-stock form, however it will be completely necessary with the winter mods that I'm currently finishing up. Curtis knows what's going on.
