Details

Catless turbo-back for the 2001-2007 GD WRX and STI. Cast-head catless downpipe paired with a 304 stainless catback, titanium-style tips. Track-only — drops the cat for unrestricted flow.

Loudest, freest-flowing of the GD turbo-back options. Bigger drone risk than the catted version, expected with no cat as a damper. Best on a built engine where the cat would be a real bottleneck.

Fitment

  • Subaru WRX 2001-2007 (GD)
  • Subaru STI 2001-2007 (GD)

Important

Off-road and competition use only. Not emissions-compliant. Check your state's regs before fitting.

Install

Day on the hoist. Custom dyno tune w/ EcuTek after install — running this on the factory map is dangerously lean.
