Wastegate Tailpipe

Chapter: C5

In Simple Terms

The turbocharger's wastegate (a relief valve that bypasses excess exhaust gas) must have its own dedicated tailpipe that connects to the main exhaust system after the turbine. This ensures all exhaust gases, whether they go through the turbine or bypass it, exit through a controlled path.

  • Wastegate exit fluids require a dedicated tailpipe connection
  • The wastegate tailpipe must join the main exhaust downstream of the turbine wheel
  • This maintains proper exhaust system integration and technical compliance
  • Ensures controlled exhaust gas management from both turbine and wastegate routes
Official FIA Text

All Wastegate exit fluids must pass through Wastegate tailpipe which must be connected to Exhaust Tailpipe downstream of turbine wheel.
