How would you classify an exhaust system with two tailpipes and two CATs?

• A. Single Exhaust
• B. Dual Exhaust
• C. Turbo Exhaust
• D. Quad Exhaust

Answer: (B)

Two tailpipes and two catalytic converters point to a dual exhaust system. The number of outlets shows how many separate paths exit the vehicle; a dual setup uses two independent exhaust routes, often each with its own CAT and muffler before the tailpipe. A single exhaust would have one tailpipe, a quad would have four, and a turbo exhaust isn’t defined by tailpipe count but by the presence of a turbocharger in the flow. So the configuration described fits a dual exhaust.
