im running 3" x-pipe from summit. the guys that put mine on had never done an f-body true dual system before and they still did a pretty good job. i only scrape when i have other people in the car over big speed bumps. as far as performance, i dont think there is a huge difference between 2.5 and 3 but i could be wrong. its about what you want really.

The dual 2.5" exhaust has a cross sectional area of equivalent to a single 3.5" exhaust. The dual 3" exhaust has a cross sectional area equivalent to a single 4.2" exhaust. Just something to keep in mind.
