Fits 2013 2014 2015 2016 Subaru Legacy 2.5L Rear Catalytic Converter Direct Fit
Welcome to First Choice Exhaust. We sell a variety of OBDII catalytic converters, manifold converters, front pipes, and flex pipes. Please do contact us for any inquiries.
Important Information:
Our products are painted in the pictures to magnify detail and to help locate the 02 sensors so it can help our buyers buy the right product for their car. When items are shipped they will not be painted because once on the car the paint will burn leaving a bad odor. Order to the fitment on your vehicle rather then the aesthetic appearance. All hardware shown in the picture will be provided. ABOUT US PAYMENT SHIPPING RETURNS WARRANTY Welcome to First choice Exhausts. FC Exhausts is one of North America?s leading exhaust supplier. All our products are made in North American factories resulting in less pollution and an overall more ecofriendly production process. We pride ourselves in delivering a high-quality product, therefore we only use high grade catalyst and only employ licensed welders. All our catalyst come in a 100% stainless steel converter body which are more corrosion resistant and can handle more heat. All our converters come with a guarantee to take away your CEL (check engine light). We strive to provide the highest quality for the lowest price.

Diagnostic report and repair proof from the original cause of the first converter failure ;
Picture of the emissions tag that is placed under the hood of the vehicle.Many times, catalytic converter failure is a symptom of an issue somewhere else in the vehicle.
It is imperative that you fix the problem that caused your OEMcatalytic converter to fail because if you don't, that same problem willlikely destroy the replacement converter as well. The warranty thatcomes with a new replacement catalytic converter will not cover the typeof damage listed below.
If your factory installed catalytic converter needs to be replaced,one of the problems below most likely contributed to its failure.
Engine Tune-Up Required
Engines in need ofservice and older engines that burn oil due to worn cylinder walls,stuck rings, and worn valve guides will produce by-products that canfoul the converter. When an engine is operating outside of the properspecifications, wear and damage may be caused to the catalytic converteras well as the engine itself. Incorrect air/fuel mixture, incorrecttiming, or misfiring spark plugs could lead to a catalytic converterfailure or worse.
Bad Spark Plugsor Spark Plug Wires
Spark plugsthat don't fire or misfire forces unburned fuel into the exhaust system.Because the catalytic converter gets very hot, this unburned fuel canignite inside the converter and could result in a partial or completemelt down of the ceramic catalyst.
Oil or Antifreeze Entering the Exhaust System.
Whenoil or antifreeze makes its way into your exhaust system creates athick carbon and soot which coats and eventually clogs the air passagesin the converter's ceramic honeycomb catalyst. This causes two separateproblems. First, these carbon deposits stop the catalytic converter fromdoing its job of removing harmful emission in the exhaust flow. Second,When the pores become clogged in the ceramic catalyst, exhaust flow isrestricted which increases backpressure. This results in heat andexhaust backing up inside the engine. The excess back pressure created can actually cause internal engine damage.Your engine can actually pull burnt exhaust gasses back into thecombustion chambers and reduce the efficiency of the next burn cycle andcreating a loss of power and overheating of engine components. Worn outpiston rings, failing gaskets, faulty valve seals or even warped enginecomponents are all possible causes of this problem.
Unburned Fuel Entering the Exhaust System.
Ideally, the fuel that powers your vehicle is burnt up in the combustionchamber. Any fuel that gets through the combustion chamber unburnedenters the exhaust system and can ignite once it reaches the catalyticconverter. This can over-heat the converter far beyond its normaloperating limit. and cause aMelt Down. Possible causes are an improperfuel mixture, incorrect timing, bad spark plugs, a malfunctioning oxygensensor, sticking float, defective fuel injector or a faulty checkvalve.
Oxygen SensorNot Functioning Properly.
If youroxygen sensor is no functioning properly it can send incorrect readingsof exhaust gasses to the vehicle's computer. The faulty sensor readingscan result in a improper (too rich or too lean) fuel mixture condition.Too rich and the catalyst can melt down from fuel burning inside theconverter. Too lean and the converter will not be able to serve itspurpose changing hydrocarbons into safe elements. This may cause yourvehicle to fail the emissions test during the annual State VehicleInspection.
Road / Structural Damage
The catalyst honeycombinside of a catalytic converter is made up of a lightweight,thin-walled, fragile ceramic material. It is wrapped in a dense,insulation mat. This mat holds the catalyst in place and provides someprotection against damage. However, broken exhaust hangers, off-roaddriving , potholes, speed bumps or any impacts underneath your vehiclecan strike the catalytic converter causing acatalyst fracture. Once theceramic honeycomb is fractured, the broken pieces rattle aroundbreaking up into smaller pieces. As a result, exhaust flow isinterrupted and backpressure in the exhaust system increases leading toheat buildup and loss of power. Corrosion, thermal shock, metal fatigue,stress fractures and stripped oxygen sensor threads are some otherissues that may require you to need a replacement catalytic converter.
If you gennerally only take shorttrips around town in your vehicle and dont regularly drive longdistances, your catalytic converter may not be getting hot enough tocompletely burn away the hydrocarbons. To prevent clogging the catalyticconverter, take your vehicle for the occasional highway drive for 15minutes or more. This will allow the exhaust to sufficiently heat up andburn off all of the deposits builtup in the catalytic converter. Please note: Labor and shop expenses are not covered by the warranty.
