## DB Killer Calculator Description
DB Killer is a practical calculator for motorcycle exhaust DB-killer design and comparison.

  Enter your exhaust and engine parameters, then adjust DB-killer geometry to estimate flow area, flow ratio, gas velocity,
  likely power loss, and approximate sound attenuation. The app also includes a sound simulator and side-by-side
  configuration comparison so you can quickly evaluate different hole counts, hole diameters, center openings, and DB-killer
  lengths.

  Features:

  - DB-killer geometry calculator
  - Exhaust pipe and hole area calculations
  - Flow ratio and gas velocity estimates
  - Approximate power loss estimate
  - Approximate dB reduction estimate
  - Sound simulator with automatic or manual baseline dB
  - Side-by-side configuration comparison
  - Metric and imperial units
  - Multiple interface languages
  - Local preference saving
  - No account required

  DB Killer is designed as an engineering-style estimation tool for riders, builders, fabricators, and exhaust tuning
  enthusiasts.

  Important: Results are estimates only. The app does not certify legal road use, emissions compliance, racing class
  compliance, or official sound test results. Always check local regulations and verify final setups with proper measurement
  equipment.
