Catalytic Converter For 2004-2005 2006 2007 2008 2009 Toyota Prius 1.5L 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. If you have any further questions, please don’t hesitate to leave us a message.

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 OEM catalytic converter to fail because if you don't, that same problem will likely destroy the replacement converter as well. The warranty that comes with a new replacement catalytic converter will not cover the type of 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 of
service and older engines that burn oil due to worn cylinder walls,
stuck rings, and worn valve guides will produce by-products that can
foul the converter. When an engine is operating outside of the proper
specifications, wear and damage may be caused to the catalytic converter
as well as the engine itself. Incorrect air/fuel mixture, incorrect
timing, or misfiring spark plugs could lead to a catalytic converter
failure or worse.
Bad Spark Plugsor Spark Plug Wires
Spark plugs
that don't fire or misfire forces unburned fuel into the exhaust system.
Because the catalytic converter gets very hot, this unburned fuel can
ignite inside the converter and could result in a partial or complete
melt down of the ceramic catalyst.
Oil or Antifreeze Entering the Exhaust System.
When
oil or antifreeze makes its way into your exhaust system creates a
thick carbon and soot which coats and eventually clogs the air passages
in the converter's ceramic honeycomb catalyst. This causes two separate
problems. First, these carbon deposits stop the catalytic converter from
doing its job of removing harmful emission in the exhaust flow. Second,
When the pores become clogged in the ceramic catalyst, exhaust flow is
restricted which increases backpressure. This results in heat and
exhaust 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 the
combustion chambers and reduce the efficiency of the next burn cycle and
creating a loss of power and overheating of engine components. Worn out
piston rings, failing gaskets, faulty valve seals or even warped engine
components 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 combustion
chamber. Any fuel that gets through the combustion chamber unburned
enters the exhaust system and can ignite once it reaches the catalytic
converter. This can over-heat the converter far beyond its normal
operating limit. and cause aMelt Down. Possible causes are an improper
fuel mixture, incorrect timing, bad spark plugs, a malfunctioning oxygen
sensor, sticking float, defective fuel injector or a faulty check
valve.
Oxygen SensorNot Functioning Properly.
If your
oxygen sensor is no functioning properly it can send incorrect readings
of exhaust gasses to the vehicle's computer. The faulty sensor readings
can result in a improper (too rich or too lean) fuel mixture condition.
Too rich and the catalyst can melt down from fuel burning inside the
converter. Too lean and the converter will not be able to serve its
purpose changing hydrocarbons into safe elements. This may cause your
vehicle to fail the emissions test during the annual State Vehicle
Inspection.
Road / Structural Damage
The catalyst honeycomb
inside 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 some
protection against damage. However, broken exhaust hangers, off-road
driving , potholes, speed bumps or any impacts underneath your vehicle
can strike the catalytic converter causing acatalyst fracture. Once the
ceramic honeycomb is fractured, the broken pieces rattle around
breaking up into smaller pieces. As a result, exhaust flow is
interrupted and backpressure in the exhaust system increases leading to
heat buildup and loss of power. Corrosion, thermal shock, metal fatigue,
stress fractures and stripped oxygen sensor threads are some other
issues that may require you to need a replacement catalytic converter.
If you gennerally only take short trips around town in your vehicle and dont regularly drive long distances, your catalytic converter may not be getting hot enough to completely burn away the hydrocarbons. To prevent clogging the catalytic converter, take your vehicle for the occasional highway drive for 15 minutes or more. This will allow the exhaust to sufficiently heat up and burn off all of the deposits builtup in the catalytic converter. Please note: Labor and shop expenses are not covered by the warranty.
