Dual Exhaust System Recommendations ?

I did a Jegs system and it is true dual. I liked it.
You can add in a X pipe or a H pipe for extra money, but, the worth of it all is only up to you. While the H or X pipe add's power and a few extended rpm for the power band, it is a hassle to do. If you can cut and weld pipe yourself, it will not be so bad.
