Im not entirely sure what the question is, so if this doesnt answer it shoot me a PM. If you mean going back to stock to avoid noise a mistake on account of lost power; imo no that wasnt a mistake. Having an exhaust thats too loud for you makes you miserable, and isnt worth whatever the gain...
...as the noise output was very loud and overshadowed my radio.
The service department is still waiting on receiving the replacement parts.
Question is was this a mistake on going back to stock to reducenoise?
