Don't bother with larger diameter pipes. You'll see a drop in low-end power from the reduced flow velocity. You're better off going with a higher-flowing muffler and catylitic converter and leaving the stock pipes in place. That's the setup I have.

As it's been stated, reducing pumping losses helps both power and economy.
