It can't the converter is in the exhaust system
yes, but it is illegal and i do not encourage it becasue your engine light will stay on, but if your converter has already damaged your engine, it is to late and you need to replace the engine. this happens because the pre cat or pieces of it get sucked up into the engine damageing the cylinders
To extract precious metals from a catalytic converter, the converter is first crushed into small pieces. These pieces are then heated to high temperatures to burn off any organic materials. Next, the remaining metal is dissolved in acid to separate the precious metals like platinum, palladium, and rhodium. These metals are then further processed and purified for reuse.
One of the easiest ways would be smashing tossing the catalytic converter around enough to make the ceramic material break into small enough pieces to fall out. I assume the only reason to do this is to eliminate exhaust back flow for better performance.
yes a bad catalytic converter can make different problem 1 if is clog is so much restriction the engine don't start or run a few seconds or few minutes and stall if the damage cat is bank 1 and direct fit some pieces reach the [ egr ] valve and can get stuck open and the engine don't start or shakes allot
Normally the heat shield on top of the converter is the source of the rattle. It is possible the the converter medium itself has broken into pieces resulting in a rattle that sounds as if there are rocks in the converter. If the heat shield and the rest of your exhaust seems secure, it is likely the converter needs to be replaced.
Because too old or get damaged If an engine is not tuned properly and allowed to run continuously, it can damage the cat by overheating and melting the catalyst inside causing an air restriction. The inside of the cat can also break up into pieces causing again an air restriction.
If it's coming from the rear, I would check either your catalytic converter or your muffler. Either could have pieces loose in them that would cause a rattling sound when you either push or release the throttle.
The cat can have a melt down and restrict the flow of the exhaust resulting in power loss. The extent of the damage determines how much power is lost. The cat can also break up into pieces and cause a blockage resulting in power loss. Depending on the year, make and model it may also illuminate the check engine light if the cat is not performing as it should.
There could be hundreds of different things that could rattle. Give us more details. A common rattle is from the catalytic converter. The inside breaks and pieces get into the exhaust and rattle.
It has been my experience, though not for the average "shade tree" mechanic, that the converter can temporarily be cut out and a straight pipe spliced in. If the converter has in fact broken down, then the vehicle will run almost like new. When the honeycomb looking internal lining of the converter gets brittle it will break off in pieces large enough to block exhaust flow and will substantially rob power. If the Blazer is used "off-road" on occasion the excessive bouncing may accelerate the situation.
Check the Catalytic converter, they start to break apart and the pieces are pushed into the pipe (restricts flow thru the exhaust system). Pull the o2 sensor and see how it runs. If it changes then the cat is bad.
I had the internal ceramic grid in the catalytic converter disintegrate into small pieces and go into the muffler. It would drive about five miles and then the check engine light would come on and loose power. It was a bear to diagnose.
