Straight pipe is dangerous for the driver, other people and the environment.
Unleaded Gasoline is 300% more toxic than leaded Gasoline.
As a driver do you want to breathe toxic fumes that will enter in your vehicle since there’s no catalytic converter?

In reply to Kim. Wow, nice work. She'll probably run a lot better now that you cleaned out that cat.

2005 Nissan Frontier king cab 4.0 V6. P0300 (multiple cylinder misfire). Replaced all plugs, coil packs, all injectors and bank 2 fuel injector pressure dampener (didn’t realize there was one for each fuel rail). When none of this worked to clear my blinking check engine lightI pulled my exhaust system. The bank 2 primary cat (passenger side) was comepletely gone. Not only could I see light, I could read a book looking through it. When I dropped the bank 2 secondary cat I found out what happened to the honeycomb in the primary cat. After dumping out as much of the clogged cat as I could, I soaked it in soapy water for 36+ hours, I forced 140 psi air through it to get it as dry as I could. Sprayed it down with the B12 aerosol let it soak about and hour. Rinsed it as best I could and repeated the 140 psi air dry. Then I took the torch to it for about 30 minutes. Max temp reading when done was about 360 degrees Fahrenheit. I can see some daylight through it. Do I stand a chance or should I just bust out all the honeycomb and reassemble. As soon as I can afford to replace the 2 cats I will, I just need my truck back on the road.

In reply to Eltee. Your catalytic converter may just need replacement. I'd take it to a shop and have them determine if that will be necessary.

I get code P0430 on my 2008 Nissan Frontier SE V6 4.0L. I changed downstream Bank 2 02 sensor per OBDII reading. Truck needle doesn’t move at idle in park or in gear, good power and no smell, burning of oil or smoking. I’ve put Catacleaner in twice and ran high octane gas through with two tank fulls. I’ve cleared the code but after driving 40-50 miles Service Engine Soon light comes on and when reading with OBDII the P0430 codes pops up again. Any thoughts or ideas what might take car of this? I also added some Bar’s Stop leak into my oil to seal up any possible leaks I can’t see. Any help is greatly appreciated.

In reply to Ananda. Unlikely, but you'll have to drop the catalytic converter and inspect it to know for sure. Sometimes the internal honeycomb element comes loose and can rattle. When this happens, you risk a clog by not replacing the catalytic converter, because the element can be lodged the wrong direction and restrict flow.

Rattling noise coming out from cat. Is it possible to clean and use without replacing new one?

If you live in a state without emissions testing, just pull the cat and straight pipe it.

What about a lye solution & pressure wash? — I don’t think it can react with anything in there since its not an acid.
