are my cats ****ed?

[matt 2LT]

i think the cats on my E46 328CI may be on there way out/collapsed, ive got the following symptoms, can anyone confirm.


a tinny rattle from the front of the exhaust section, while idling.

and a louder metallic rattly sound while under load.

engine seems a bit down on power at low revs.

and bit of a nasty weird burning smell coming out of the exhaust.


cheers

Doesn't sound like it, cats make one hell of a racket when fked due to the male have a barb on the end of their penis which actually hurts the female. (true)

(but yes, possibly/probably, collapsed matrix perhaps?)

can anyone else confirm that the cats have collapsed?


also what is the difference between a ceramic and steel cat?

i can get a ceramic one for £236+vat or a steel one for £374+vat

Or a decat pipe for circa £50. I know what I'd be buying.

If you suspect it is, get it checked ASAP as the back pressure from a full collapse CAN cause catastrophic engine damage - think bent valves.

Asking for an internet diagnosis is about as much use as an ashtray on a Ducati.

Get it to a garage for a professional opinion.

If you can, get under the car and give the cats a good hit, if you can hear a rattle then they probably are buggered.

Just dont do it after a long run as they get bloody hot!

[dudleybloke]

the car is completly fhooked........
i'l give you £5 for it.

Does sound like the symptoms of a failed cat. However it may be a baffle in the exhaust broken up or similar? Needs taken to get looked at sooner rather than later in my opinion.
