You guys are way overstating the "problem" of 3" aftermarket exhausts. A 3" system is likely to actually improve the power curve for the way most people drive these anyway as a larger system might actually lose you some torque in the middle of the power curve where you don't want to. If you don't at least have a whipple or similar on your 6.2L then I think you are kidding yourself about exhaust and the effect of larger pipe.
As far as Duramax's go I've personally seen more than one "sleeper" LB7/LBZ Duramax making well over 500whp on the factory 3" exhausts (I really think 600whp+ but I'm being conservative). My LB7 with a built trans and upgraded turbo stood no chance even with my giant 5" exhaust.
