'75-76 Dart Sport 360, why hp so high?

I can follow these arguments for the 1974 Sport 360......but if these cars did get a cat in '75 for most of Detroit when that cat step happened it was accompanied by a restrictive single exhaust and a BIG fall in SAE net power ratings. How did Mopar not follow that trend in 1975 with the Sport 360? (Even 1976 the engine is still at 220 hp).

I do recall reading that Mopar was only committing to having 80% of its production with cats for 1975.....also in other Mopar lines (say Road Runner) 1200 or so cars got ordered with a "cat delete" option. Cop cars also had cat delete so they could still catch the bad hombres. So past or present Sport 360 owners what do you know / remember about the exhaust systems in these cars....1975...76?
