Which header quickly bolts on and off and contains bungs and connections for exhaust?

• A. Dyno Header
• B. Stock Header
• C. Zoomie Header
• D. Custom Header

Answer: (A)

Headers used for dynamometer testing are built to be swapped quickly and to include ports for exhaust sensors. A dyno header is designed so you can bolt it on or off with minimal effort, which is essential during testing when you need to pull it off between runs or swap setups. It also commonly includes bungs and connections for sensors such as O2 sensors, pressure taps, or other probes, so you can collect accurate exhaust data without improvising connections.

Stock headers are designed for production vehicles and prioritize fit and noise regulations over rapid changes or multiple sensor points, so they’re not optimized for quick removal or sensor installations. Zoomie headers are a style of short-tunnel tubes that route differently for performance, not for easy swapping or sensor integration. Custom headers can be built to fit and sometimes include sensor ports, but the standard dyno header is the option explicitly designed for quick changes and built-in sensor connections.
