02-07 WRX & STI Invidia Downpipes

Invidia offers downpipes for the 2002-2007 Subaru WRX & STI that are designed in three different configurations. Every Invidia WRX & STI downpipe features 3" diameter stainless steel piping, thick flanges, and a cast upper section for optimal flow, performance, and longevity.

Invidia's catless downpipes will cause a Check Engine Light (CEL) on your 02-07 WRX or STI. While this isn't harmful, it can be annoying and disables the cruise control, but you can use a software solution such as the Cobb Accessport to eliminate these codes and make more use of the newly available performance the Invidia downpipes offer. The high-flow cat Invidia WRX & STI downpipe is not emissions legal, and may still cause a CEL, but it does help to reduce boost spiking on 2.5L cars.

 Invidia now offers 2 bung versions of downpipes to make tuning easier! A plug is included so you don't have to run two sensors immediately.


  • Note:
  • 3" exhaust gasket included, turbo to downpipe gasket sold separately.
  • FITMENT:
  • Subaru STI 2004-2007
  • Subaru WRX 2002-2007
