Did you buy a genuine part?and even if you did, toyota buy in exhaust components, so different makers will be slightly different re bore size,the ONLY way to make sure all the parts of the exuast fit, is to buy the complete system,if you cannot modify the pipes to fit.... please do not try to weld a cat onto a pipe.....

Last time. I have Ford focus 2003 sedan dohc 2L. I lost a part from exhaust system. from back to front I see 1. tail pipe 2. rectangular box shaped part? Lunch Box? 3. missing part Muffler?


Starting from the front, coming off the exhaust manifold should have, 1. Exhaust pipe, 2. Catalytic converter, 3. Exhaust pipe, 4. Resonator, 5. Tail pipe. Also, there should be an Oxygen sensor somewhere around the catalytic converter.

Hard to start. Also, feels like vapor locking. Stalls while running or driving.


If the car runs for a while and then stalls you should suspect that internal parts of the catalytic converter are lodging themselves in the exaust pipe between the first catalytic converter and the second or between the second converter and the exhaust pipe muffler. When the catalyst chunks partially block the hole the car will stall. To test, try opening the exhaust after the first converter just enough to make it really loud and try driving it to see if the problem disappears. If it does you will have to remove pipe sections until you find the catalyst chunks and remove them.

How di I replace a catalytic convertor


Replacing a catalytic converter ranges from easy to moderate for most DIY mechanics. It is best to take off the entire exhaust system (not the exhaust manifold or headers) for a through inspection when doing this job as a bad catalytic converter is a sign that other parts of the exhaust system may be requiring replacement as well including the muffler(s) and tail pipe(s). Tenneco's Walker Muffler site has detailed schematics for both domestic and foreign cars. TRW Aftermarket may carry them too. (If you own a very expensive car; you plan on keeping for a long time , see about a stainless steel exhaust system... Borla, Remus, Supersprint, Bosal, and ANSA make many for foreign cars.) The other thing(s) to check and remove before taking the exhaust pipes off are the 1 or 2 Oxygen sensors... they will affect your gas mileage significantly. Unplug the wires to them and unscrew the front one and look at it. If it's filthy fouled replace it and the lower (if there are 2) one too... the information from both of them influences the car's ECM/ECU computer to adjust the air/fuel mixture.. (NGK, Beru, and Bosch make oxygen sensors for most cars.) Ensure you buy new exhaust pipe hangers and mounting bolts, if your hangers don't include them. Use Penetrating oil on a COLD exhaust system to help free up the bolts that join the lower part of the exhaust manifold to the first part of the exhaust system. Letting it sit overnight seems to work best. You may need a new gasket there so prepare and buy a new one to replace it. (When replacing, tight is good, too tight is bad as you may break off the stud or bolt.) IMPORTANT!!! Old catalytic converters need to be disposed of as hazardous waste as they contain several gridded wafers of electroplated platinum base metal. (Contact the new catalytic converter seller to see if they will take your old one or contact your city or county disposal office to see how to properly dispose of a used one.) Exhaust pipes typically fail where there are bends as the metal is stretched and thinner there... look for holes and rust. Typically, a ratchet set, rubber mallet and hacksaw may be required to cut a catalytic converter out and then crush the round inner sleeve remaining inside the exhaust pipes ends with a thin flat chisel, pulling it out of the "good" exhaust pipes using locking pliers (a.k.a. Vise Grips tm). (Alternatively, a rubber mallet may be used to strike the catalytic converter to break it loose from the exhaust pipe ends... DO NOT DO THIS if the catalytic converter is in the disintegration stage. Do Not use the mallet on the exhaust pipes as they will bend!) Use crocus cloth or sand paper to smooth the inside of the exhaust pipe connections and ensure by trial off the car that the new catalytic converter goes in the pipe ends easily before mounting the separate pieces on the car... terrible to learn it won't go in, due to carbon soot or rust when you're on your back underneath!

When replacing your converters you can eleminate the second converter, shops in different states have different rules that may prevent them from losing the 2nd converter but you as an end user can but an aftermarket converter that will fit your car and install it yourself. This will require a sawzall or a good hacksaw to remove the old units so as to leave enough pipe coming down from the exhaust manifolds for the new converter to clamp on. Once the new converters are installed any muffler shop can hook up the rest of your system.

How to fix muffler exhaust?


New exhaust would be the best way to go. Maybe from the catalytic converter back. You can get muffler tape at your local parts store but it wouldnt be permanant nor will it pass inspection.

Loud muffler noise up front of vehical.what is


If the noise sounds like your muffler, but isn't coming from the area of your muffler, then you have an exhaust leak upstream from the muffler.

From the front of your muffler, follow the tubing forward to the catalytic converter, then forward to the engine exhaust manifold.

If you start with the car sitting for a few hours to make sure it's cold, you can use your hand to feel for blowing leaks while the engine is running, but chances are you'll be able to hear it. be careful of the catalytic converter itself, as it heats up fast, so check that first.

Once you've found the leak, the fix depends on the emissions laws in your state. If you have none, and the leak is in the middle of the pipe, you can buy pipe patchers (metal preferred) through auto parts stores or catalogs/websites. If you have strict emissions laws, or the leak is at the junction of the catalytic converter and pipe, you'll need to replace the failing part.

My car is loud!!!


If you take it to a muffler shop, like Meineke, they should be able to give you a free inspection and quote. It will PROBABLY be as simple as welding up a small hole in either the catalytic converter or the muffler.

Good luck!
