Hi,

On a cold start, I got under the car and in the first 10 seconds (so I
didn't burn my hands off) I felt the exhaust chamber under the car
(not the pipe).. I swear is sounds like there is something IN it,
raddling around.

I had a similar experience, which was resolved here thanks!, where it
was the heat plate being loose, but I can't find any missing bolts on
the heat plate.

Could I be missing brackets the keep the exaust in place?
Can anything actually get in there??? Doubt.

Thanks for your help

Erik

Insides of the catalytic converter can certainly break up, causing a
'rattle'. Not sure about a 'raddle', though....

You should probably wait for a more authoritative answer, but my guess
is..

1) the internals of the catalytic converter are rattling around until
they come up to operating temp, and

2) don't worry about it.

Thank both. It is definately something inside, no doubt. It does not
go away have it heats up. So I'm hoping this is not a replacement :-
S, do you think I can take it out and open it out. or no way?

thanks
