I think the only pistons now with offset are the dead stock cast pistons. The cheapest ones money can buy. I believe once you jump up to hypers they are centered and of course forged. I think you'd be hard pressed to hear the difference between one with an offset pin and one with a centered pin. That's really the only reason they were ever offset was to reduce noise. I think with all the other noises an engine makes it'd be tough to hear. Now floating pins with forged pistons with plenty of clearance is another story.
