Active Autowerke's Signature AFlow downpipe replaces the restrictive factory downpipe on the GR Supra 3.0. It keeps a catalytic converter, using Active's own AFlow cat, while letting the B58's turbo breathe more freely.

What you get

  • Catted downpipe with Active's AFlow cat.
  • Less restriction than the OEM downpipe.
  • Turbo flange gasket included and pre-fitted in the flange, since installers were sometimes damaging it.
  • No performance tune needed, according to Active Autowerke.
