Show a diagram of 1988 mustang exhaust system?

Answer 1

Well, all naturally aspirated vehicles have the same general components to an exhaust system. It starts with an exhaust manifold that attaches to the engine block. The manifold then attaches to a "mid-pipe". This "mid-pipe" is where the Catalytic Converters are housed. These Catalytic Converters control NoX gases and are the emission control device within the exhaust system. From there exhaust crosses over via an "X"pipe or "H"pipe(the X looks like an X and the H looks like an H) and enters into the mufflers. These mufflers can be chambered or straight through, the latter being the better performing of the two. Finally it leaves the mufflers out the tailpipes. A general diagram can be found here:
