CLOGGED CATS REALLY BAD

474 Views 15 Replies 11 Participants Last post by  Logan71
I have a clogged cat been driving on it for months now it’s worse in gas mileage power and it sound like a miss in the engine just wonder what route I should go should I just replace the cat.? Should I take the cat off and run like that or should I gut the cat ?

You should install headers with high flow cats.
well... there is the chance that if you keep driving that way... you'll eventually be catless anyway.

or start a grass fire.

If you know that you got a clogged cat. I wouldn't be driving it. Nows the time for headers to be installed. I say this because I just checked rock auto. You'll have close to $400 per bank plus your time if your just gonna replace both banks of cats. Might as well enjoy more power and put headers on. Just my opinion.

Stop driving it before your repair bill rises exponentially.

If it becomes too clogged, all the exhaust gas will be forced backwards into the engine.

Back pressure on an exhaust always = iNO BUENO!

That's probably illegal in many states. You may find pockets of people that do that, though. I've heard Cat Fried Rice is an acquired taste.
