Fitment Details: This exhaust donut gasket is a perfect fit for 2002 - 2025 Subaru WRX, 2004 - 2021 Subaru STI, 2005 - 2009 Legacy GT, 2004 - 2022 Subaru Forester, and 2005 - 2022 Subaru Outback. Features: It's an OEM 'donut' style gasket that sits between the lower downpipe and midpipe of the stock exhaust system for Subaru WRX or STI. It's super useful if your gasket gets lost or damaged during installation, or you just want to put in a new one as a precaution. While many aftermarket exhaust systems use flat gaskets, Cobb Tuning and Borla exhaust systems need you to keep this stock 'donut' gasket. Also, it's required when using a downpipe adapter with a 3 - inch flat flange downpipe. Warranty Disclaimer: Subaru of America only warrants parts installed on a car with a matching VIN. California Prop 65 Warning: Working on, servicing, or maintaining a passenger or off - highway motor vehicle exposes you to chemicals like engine exhaust, carbon monoxide, phthalates, and lead, which can cause cancer, birth defects, or other reproductive harm.

Using your Subaru exhaust donut gasket is easy. First, locate the area between the lower downpipe and midpipe of your Subaru WRX, STI, Legacy GT, Forester, or Outback's stock exhaust system. Carefully place the gasket in position. Make sure it fits snugly. When installing, be gentle to avoid damaging the gasket.

As for maintenance, check the gasket regularly for signs of wear or damage. If it looks worn out or is damaged, replace it right away. And remember, Subaru of America only warranties parts installed on a car with a matching VIN. Also, be aware of the California Prop 65 warning. Try to avoid breathing exhaust fumes, don't let the engine idle longer than necessary, service your vehicle in a well - ventilated place, and keep your hands clean by wearing gloves or washing them often while working on your car.
