3" or 2.5" Exhaust ?

I'm going to upgrade to a full TTI X-pipe system. Do I stay with the 2.5" system and re-use my 2 chamber Flowmasters, or should I go with a 3" system and use the Dyno-Max mufflers? I think the 3" is overkill for my conservative engine combo, but sure would look nice. But I'd rather have it run good ....



Opinions Please. :-k
