What\'s in the Box 1× Muffler Pipe Exhaust System Complete assembly (resonator pipe and rear muffler). Important Installation Notes
- Converters are designed to last the life of a vehicle. If your converter needs to be replaced, it may be due to an emissions error or problem in your engine tuning. Converters that overheat because of engine problems may turn blue or bronze. These problems must be corrected BEFORE installation of a new converter.
- Any modifications of any kind will void all warranty coverage for this item. Warranty is voided if the catalytic converter substrate is melted or broken — this is due to an issue with the car itself and not the catalytic converter.
- Cosmetic flaws may be present. Due to its size and shape, this item may encounter cosmetic flaws during its stocking and shipping process. The powder coating finish is designed to add shelf life by minimizing surface scratches, which may deteriorate over time due to temperatures reached once in use.
- Damage from misuse is not covered. Products damaged as a result of abuse, misuse, improper repair, improper installation, alteration, or modification will not be covered by the warranty.
- Replace your O2 sensors at the same time. O2 sensors must be replaced when you replace the converter, or the warranty will be void. We have determined that failure of either the front O2 sensor (the front wide-band sensor, also known as an Air-Fuel Ratio Sensor) or the rear downstream sensor can trigger a false P0420 code. Both sensors should be replaced when you replace the converter.
⚠️ Warranty Notice: Modifications, improper installation, or failure to replace O2 sensors will void warranty coverage. ✔ Direct replacement for 2009–2013 Subaru Forester / Impreza 2.5L | ✔ 409 stainless steel | ✔ Bolt-on install Payment Shipping Returns Contact Us 1.We suggest that ask professional to install products and contact us when installing issue happened.
