Guys I’m thinking of cleaning both my CATS. And by clean I mean, removing them and cleaning them at a specialist shop. They will put the cat in a chamber, connect a hose to it and pass high pressure cleaning liquid through it.
wanted to know if it’s good or bad.
On a side note, - I get a nasty odor after I accelerate hard

Never heard of it. But in theory sounds legit. Would be nice to get a before and after pic to see if it truly works. Good luck brother!!!!

Looks like the water cleans up. So you could "ASSUME" it works. Would be nice to see a inside pic before and after. Can you see some daylight after the cleaning? How much do they charge?

I will get a before and after picture when I go for it. Probably in Jan. They charge 35BD for one CAT. That’s I guess around 90$

Cats run at over 1000 degrees f and are self cleaning. The only reason a cat would be "dirty" or degraded is due to long term engine issues such as burning oil or constant misfires.

This seems like a solution to a problem that does not exist

If you don't have any running concerns or fault codes present, then there is no point. If it's a sulphur smell that you get from the tailpipe, then try filling up at a different gas station and see if that helps.

i get the smell inside the cabin thats the prob. Tried changing the fuel(premium, standard) and fuel station, still no difference. smell comes after the car is warmed up and i accelerate above 4k rpm

That smell could be caused by anything, I would get a mechanic to look at your Jeep before you go and possibly waste money on something that is not required and may cause more issues. If you're sure it's a cat problem then go ahead, I hope it works out well for you.

Not knowing the country of origin of the post, could it be that one of the local gas stations is selling an inferior and contaminated gasoline to sell at a cheap price?

I question fuel quality. I also question an exhaust leak. Do you ever have a CEL ?

Fuel is kinda fuel. It's like saying different oils off the shelf are different. They all go back to about three different manufacturers. Then they all put a different label on it and say theirs is better. Maybe you just need to put, what we call, a good Italian tuneup on it. Meaning, put the hammer down on it and burn it clean!!!!!
