This is the Invidia Lower Catted Divorced Wastegate w/2 Bungs Downpipe. The factory downpipe is highly restrictive by the nature of the design and begins right after the turbocharger leaving much room for improvement. Invidia really opens up the exhaust flow path with their downpipe by developing a unit that combines a larger piping diameter with smooth bends. This will allow the turbocharger to exhale those exhaust gases with fewer restrictions and turbulence for unobstructed flow right out of the cat-back exhaust system. Because of these reasons, downpipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque with a great reduction in turbo lag.


  • 304 stainless steel construction
  • Divorced wastegate flange option separates the exhaust flow exiting the turbocharger
  • 3" piping diameter
  • Built-in high-flow catalytic converter at the lower-end of the downpipe
  • Designed with an extra O2 sensor for those adding an aftermarket wideband sensor
  • Includes new exhaust gasket and hardware to connect the rear to the cat-back
  • Increases horsepower
  • Increases torque
  • Reduces turbo lag
  • Improves the throttle response
  • NOTE:

  • TUNE REQUIRED - Because aftermarket downpipes will change the power dynamic of your vehicle, a tune is mandatory to optimize the power and running condition of your vehicle
  • Does not include the turbo flange gasket - It is highly recommended that you source a new gasket before the installation
