Default 2008 1.6vti 308 with a Rattling Cat

Hi to all,

newbie to this forum and all things Peugeot, so may be asking a bit advice from time to time, from those a bit more experienced with these cars.

Have owned the 308 about 5 months with just over 60k on the clock, a few issues have become noticeable, the Cat rattles after warm up, and was told to "best just ignore it" when I took it back to the Trader to actually have a front coil spring replaced under warranty. He did point out the Cat wasn't covered.
since then there have been worsening performance issues, lack of power and throttle response mainly in the lower rev ranges. although there are no fault codes showing at all which I would have expected.

So is a new Cat is needed?
Does anyone know if the cheaper ones are any good or If they should be avoided ?(limited budget)
and is there is anything to be aware of before replacing it as I will be doing it myself.

Thanks

.

So this is just an update to my own post for those who read it, or might have a similar issue with there car in future.

Although not having a response to my post for possible advice. I went ahead with replacing the Cat. And I actually opted to buy a used one as money was limited and it did come with a warranty.

When I got the rattling one off, it was plain to see that a lump of the ceramic honeycomb material was lodged in the downpipe part of the Cat which was obviously causing a partial blockage of the exhaust gases and likely back pressure, which would very likely account for the performance problems. Although I had already started to suspect this would be the cause, but I was still puzzled by the lack of fault codes.

So with the replacement Cat on, performance has returned to normal with no rattling, and I am very pleased with the result.

So if anyone does have a suspected rattle in there Cat, replace it, preferably with a new one.
Don't just ignore it as I was told to do by a so called mechanic.
