my car has a strong odor at high rpm with some black smoke coming out of the exhaust too. it still has real strong power but it stinks real bad i just put on a used cat converter and it doesnt seem to be holding back any power from my car. anyone have any suggestions??

 

a used converter? high-flow or stock? could be a bad converter.

 

used stock

 

if its bad is there any way i can clean it?

 

Unfortunately,no you can't clean a cat...you need a new one. There is special mesh material and such inside a cat that help convert exhaust fumes and I guess overtime that material looses it's ability to catalize the fumes into supposedly H20 and CO2...well that's the theory behind a cat, you actually do get COx and some NOx.

I thought that emissions warranties extend above a certain time period, I wonder if you can get Honda to replace it for free?

 

unfortunately, converters on a non-tuned engine (such as yours) will eventually burn out and rattle and clog, etc. if this converter came from a car with bolt-on's and no tuning, then its probably burning out the element inside.

that's what happened to mine.

 

So smell coming from hi-flow converter, would be the fact that its "hi-flow"?
