Catyletic converter pellets

The plug in my cat converter fell out and the pellets fell out also. Is it necessary to put all the pellets back or can you run the cat without them? What are the consequences? Thanks

Re: Catyletic converter pellets

you can run it without the pellets but when i did that(pulled the plug on purpose) i couldnt get the plug to stay in and it sounded terrible. ended up having a shop put on a new style high flow cat. it wont hurt anything to run it like that though.

Without the pellets it's effectively "not a converter" anymore. If you need the cat to pass smog tests, have a high flow replacement welded in. Otherwise, replace the plug and enjoy the free flowing exhaust.

A good crossthread is better than Loctite any day.

Life is not about what you have, but who you have to share it with.

I have been told the large freeze plug for a 350 works well for a substitute plug.

The less pellets the less effective it is (catalyst). The new 3 way monolith cats are better.
