What are the differences in a caprice with twin tail pipes and a single one?

Jarvis I think only the Caprice SS have twin tail pipes. If thats not the case then I would assume that the twin tail pipes came with a more powerful engine and trim level.

I own a 1995 cprice sedan w/2 tail pipes, engine is 5.7L(350cc)More power that the average Caprice in that year.

dual pipes on a caprice from the fatory indicates the 9c1 police package or taxi usage. also to the person that replied below if your caprice had a 350cc engine it wouldnt even move chief, what u mead to say is 350 ci or 5.7l or 5700 cc big difference.

Dual exhaust is a 5.7L Single exhaust is a 4.3L
