Invidia Downpipe - Catted w/ Extra O2 Bung - 08-14 Subaru WRX, 08-21 STi, 05-09 LGT & OBXT MT

PLEASE NOTE, if installing onto a Legacy or Outback w/ stock VF40 or VF46 turbo, you may need to trim the divider flange. Please confirm full actuation of the wastegate before finalizing install and trying to tune the vehicle as you will experience extreme over-boosting issues and possibly cause damage.

For automatic vehicles, this downpipe will bolt up to the turbo and catback etc, but may have fitment issues with the transmission bracket etc. For more information, please contact Support@TurnInConcepts.com.

Upgrade your Subaru with the Invidia Catted Divorced Wastegate Downpipe featuring 2 bungs. The factory downpipe is inherently restrictive, beginning right after the turbocharger and leaving room for significant performance improvements.

Enhanced Exhaust Flow and Performance

Invidia addresses these limitations by designing a downpipe with a larger piping diameter and smooth bends. This setup allows the turbocharger to expel exhaust gases with fewer restrictions and less turbulence, resulting in a more efficient flow through the cat-back exhaust system. The inclusion of two bungs enhances flexibility and compatibility with various sensor setups.

DETAILS:

• 304 stainless steel construction
• Divorced wastegate flange option separates the exhaust flow exiting the turbocharger
• 3" piping diameter
• Built-in high-flow catalytic converter
• 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

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
