Research on Catalytic Converter for Subaru Impreza

As clean as you think your Impreza is, the exhaust coming out of the pipe is nothing compared what leaves the engine. The exhaust leaving the engine is extremely toxic and full of noxious gases that can damage the health of people who breathe them in as well as harm the environment the gases are released into. A clogged catalytic converter usually cannot be repaired; it must be replaced, but when you install a new catalytic converter, your Impreza will run better and be legal to drive.

What is a Catalytic Converter?

The job of the catalytic converter is to make the exhaust leaving your Impreza safer than the exhaust leaving your engine. If your Subaru just released the gases from the engine into the air, it would send out pollutants such as hydrocarbons, nitrogen oxides, and carbon monoxide. These are all extremely dangerous for the environment, especially when multiple cars are releasing them at once. A catalytic converter uses high temperatures to change the forms of these pollutants into less dangerous products. Hydrocarbons can be broken down into water and carbon dioxide, and carbon monoxide gets another oxygen to become carbon dioxide as well. Plants thrive on both carbon dioxide and water. Nitrogen oxides are broken down to nitrogen and oxygen, which are less dangerous than the original.

Emissions Laws and Catalytic Converters

Because they are so effective at reducing emissions, catalytic converters are required to be installed on vehicles driving in any of the 50 states, but some states have stricter laws on emissions and require additional catalytic converters to be installed to further reduce pollutants. California and New York are examples of states that may require additional catalytic converters or cats that reach those states' strict standards for controlling pollution. Check your individual state's laws to see if you are required to have a specific type or number of catalytic converters on your Subaru Impreza.

Signs of a Damaged or Failing Catalytic Converter

You may find several signs that you need a Subaru Impreza catalytic converter replacement. A clogged catalytic converter could affect your engine performance, just as anything that slows down the exhaust moving out of your Impreza does. Usually, the check engine light will come on, and it will log a trouble code with one of your Impreza's catalytic converters. This is the surest way to know if you need a new catalytic converter or a new O2 sensor, which may show similar symptoms of failure as a catalytic converter.

Subaru Impreza Catalytic Converter Replacement Cost

Most people opt to take their Subarus to a mechanic to replace the catalytic converter. The cost depends on several factors. On most models, you have both a front and rear catalytic converter, and the location of the cat, your model year, and your mechanic's usual charges for labor all affect the price. For instance, a front 2009 Subaru Impreza catalytic converter could cost from $516 to $903, but if you need a rear 2002 Subaru Impreza catalytic converter, the price lowers to a range of $477 to $853. These are high prices, and most of the price estimate is for the parts. To painlessly save money on your new catalytic converter, shop at PartsGeek.com for low prices and compatible cats for your Subaru Impreza.

Purchased this, along with other Bosal exhaust pipes, to replace my entire exhaust from turbo to muffler. Afterwards, took the car for an emissions inspection, and it passed. - Good exhaust
