Yes, and is one of the major reason why OE's have to detune engines to meet them. However, aftermarket tuning does not. So just because the aftermarket increases power by tuning out these emissions does not mean it reduces the reliability of the engine like what was inferred earlier.

Some categories you can get away with multiple power outputs which many times the manufacturer will take advantage of by charging more for the higher power unit. Similar to what Cummins does with the 6.7L and how the regular output is 370hp/800lb-ft and the HO version is 385hp/930lb-ft. Or an even better example is the new X15 efficiency series which ranged between 400-500 hp versus the X15 performance series which ranges from 485hp to 605 hp. They are the same internally aside from injectors and turbos.
