wut size piping is best for a 99 5.2 durango? 2 1/2 or 3 inch?

I have 2.5" with the mods listed below, works well. I guess it depends on what you have changed and how much you plan to change. Custom fabrication will be more expensive, I stuck with the factory pipe (which is good stainless steel) and cut in a performance muffler.

The 3" won't flow that much better than the 2 1/2. If you don't plan on having a super charger installed, the 2 1/2" will be fine.

Stick with the factory mandrel bent 2 1/2 inch.
