To much exhaust flow?

im just wondering, if i were to go with a 3" X pipe, which would replace the center muffler and replace the rear mufflers. would that be to much flow and would i be losing power? i was told not to go any bigger than 3", also with the added CAI, would that solve that problem? can anyone answer my question?

The CORSA is 3" all the way back with a straight through muffler. I am running the Lingenfelter CAI with this exhaust and it runs great. On another forum a fellow ran 316hp at the wheels. Before the mods, he ran 295hp at the wheels. And, his torque improved across the power band.

thanks for the reply, today was my first dyno...with a new era intake and a 3" cat back custom exhaust, it came out to be 345hp. i was expecting a little more, but i was told it might be from the 3" exhaust or the new "super 40's" from flowmaster. i had a real hard time choosing the right exhaust. Im looking into cam and some head work, after that i will look into changing me exhaust.
