What is a short stack exhaust system?

• A. Exhaust with multiple mufflers.
• B. A fully enclosed exhaust system with a large muffler.
• C. Open exhaust tubes with no mufflers.
• D. Jet exhaust with afterburner.

Answer: (C)

Short stack exhaust systems use short exhaust tubes from each cylinder that vent directly to the atmosphere with no muffler. This keeps the exhaust path very short, making the system simple, lightweight, and inexpensive, but it also results in a louder exhaust and more heat near the engine area. The other designs involve mufflers or enclosed paths, or are for a different type of engine altogether, so they don’t fit the description of a short stack system.
