I personally wouldn't bother with 3" unless it's a turbo car with only a 2L engine.

For all motor? might give you like 1-3hp up top at most (might be no gain or 1-3 hp loss... you'll lose tq tho for sure. I figure 2.5 or 2.75 would be the sweet spot. Probably 2.75 if I plan on turbocharging later.
