Invidia Downpipe - Catted - 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.

Invidia maximizes the exhaust flow path by developing a downpipe with a larger piping diameter and smooth bends. This design allows the turbocharger to expel exhaust gases with fewer restrictions and less turbulence, resulting in unobstructed flow through the cat-back exhaust system. These improvements make downpipes one of the most popular exhaust upgrades, providing a substantial increase in both horsepower and torque and significantly reducing turbo lag.

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
• Built-in O2 sensor bung
• 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
