The Subaru Imprezza STi is a popular sport rally car.  It features a turbocharged 4 cylinder engine and is designed for serious performance enthusiasts.  Because this car appeals to tuners who plan to use it for racing or just to impress friends, it is not uncommon for the factory converters to be removed to accommodate larger freer flowing exhaust system.  This type of modification is not only illegal for street use, but results in a car that can no longer pass emissions and will have a constant CEL with a P0420 code.  Some users will attempt to resolve these codes with high flow aftermarket converters from any one of the popular brands only to find that they do not resolve the CEL issue.
The original dealer setup can be expensive, costing $1500 or more.  We are prepared to offer a lower cost solution that actually works.  Our assembly bolts in just like the original factory part.  Don't waste your time or money with lower cost products that do not resolve the problem and only serve to lighten your wallet. This unit will make your car street and smog legal, and restore the vehicle to a stock type setup for much less than dealer prices.
Now features our advanced  ECO-III  catalyst with Nano Technology.  This product contains more precious metals than other products on the market.  We have determined that a high rhodium content is required to make a good OE replacement that won't kick the light back on.  Don't be fooled by the low prices or claims of other products, our unit is engineered to work where others fail.  Check your emission sticker.  If your vehicle is CA emission compliant and or meets Low Emission Vehicle requirements, this is the part you need.
Not legal for sale in California. If your vehicle is registered in California or New York, do not purchase this part. If your vehicle meets California requirements, but is not registered in California or New York, this converter will work on your vehicle.
I live in California, will this converter work on my car?
No. Within the state of California, special emission laws have been put into effect that require that only state approved converters can be used on replacements on vehicles that will be registered in California.  These certifications are approved on an application/engine family basis.  However, these guidelines only pertain to vehicles that will be registered within California.  So if your car is registered in California, you have little choice but to comply with California regulations.
I do not live in California but my car says it meets California requirements, can I use this converter?
Vehicles that have a California emissions sticker are designed to meet the stricter emission requirements of California.  Vehicles that meet California requirements do not need to have California legal converters if they are registered outside California, however the stricter emissions standards do need to be taken into consideration.  We strive to take the guesswork out by making sure that our converters will work on the intended application whether it meets California requirements or not.  Our converters work on all FED and CA emission vehicles and are legal for installation in all 49 states excluding California.  Our converters would technically work in California as well, but we cannot sell them there for legal reasons.
What you need to know about the Subaru models this part is designed to fit
Subaru, like many foreign automakers, builds their cars to very exacting and strict tolerances.  One result of this exceptional quality is that many replacement parts must meet these strict standards.  Catalytic converters are no exception.  If the replacement converter does not perform like the factory converter, the vehicles onboard diagnostics will likely detect that the part is not performing as well as required and a subsequent P0420 code (Catalyst efficiency below threshold Bank#1) will be set.
How is this product different?
We have taken the extra steps to make a product that actually works.  We have developed a proprietary  ECO-III  catalyst with Nano technology which is based primarily on rhodium, the most powerful and most expensive of the precious metals, instead of palladium like competitors use.  Contains up to twice the rhodium content of the leading competitor.  The result is a converter that outperforms anything else on the market, while still being less expensive than the original factory part.  
Special notes to installer
While we have taken every design precaution to ensure that this product will function correctly on the vehicles listed, it must be made clear that the original converter did not fail due to age or mileage.  The factory converter is designed to last the lifetime of the vehicle.  It has no moving parts and  does not errode or otherwise wear out. The factory converter likely failed due to a fuel management problem or from chemical contamination due to impurities found in some fuels.  The converter can only handle certain amounts of unburnt fuel.  If the vehicle is running too rich, or if the combustion is not consuming most of the fuel before it enters the exhaust, the converter can be overheated or otherwise damaged.  It is for this reason that the vehicle should be properly tuned on a regular basis.  O2 sensors should be replaced every 80,000 miles, spark plugs every 60,000 - 100,000 miles, and the injectors and combustion chambers should be cleaned with a product designed for this purpose every 10,000 miles or every year.  Use of an incorrect octane fuel may contribute to the formation of deposits in the converter, which can harm the catalyst.  Use only the octane recommended in the owners manual.  Only OE spec spark plugs and wires should be used, as other brands may cause poor combustion and contribute to deposit formation.
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 or downstream sensor, can trigger a false P0420 code.  Both sensors should be replaced when you replace the converter.
This part is backed by a full 5 year/50,000 mile emissions warranty.  This means that so long as the vehicle is kept properly tuned and maintained to the manufacturers specifications our warranty will provide a replacement converter.  We sell a better quality product, and we are not afraid to stand behind it.  There are terms and conditions with this warranty, please see the included warranty information card.  In the unlikely event that you have an issue with one of our converters, please have your sales receipt handy so that we can look up your transaction. We do not refund labor or other installation costs.
EPA approved for all Federal and California compliant vehicles, including Low Emission Vehicles* in all states excluding California and New York.  Not legal for sale in California or New York. If your vehicle is registered in California or New York, do not purchase this part. If your vehicle meets California requirements, but is not registered in California or, this converter will work on your vehicle.
*These converters are designed to work on a wide range of applications where conventional converters do not work.  LEV compliant converters contain more catalyst than regular converters, plus have specialized coatings which enhance low temperature operation without compromising thermal resistance.  This makes these converters suitable for newer cars and trucks, CNG vehicles, California vehicles located outside California, and special purpose vehicles.
