The 6 has recently developed a loud rattle from underneath the car at about 3200rpm.

So I decided to jump underneath and inspect the exhaust system. Never really paid attention to what the system comprised of. I think it is all Peugeot except for the cat..some advice needed.

The middle muffler/centre section (I think that is what it is called?) has a hole it in about half the size of a pea. When you tap it, something rattles inside. What is inside the middle muffler? The exhaust is all centered and heat shields are secure. I'm not sure if I have a cat haha..can someone let me know from the pics, it doesn't look standard. The only other thought i had was that the baffle inside my cat could have failed if I have one. Either way the middle muffler/centre section needs to be replaced, it is connected to the long piece of exhaust pipe that goes to the rear silencer....all one piece...can you get these from pug?

Excuse the stupid annotated pictures lol

Looks like either a sports cat or aftermarket cat to me.

Unless its a decat made by someone that is visually challenged.

There is a Kind of gold honeycomb structure inside cats. When a cat is knackered it will start to break apart and rattle. If its rattling on throttle I'd say its knackered and I'd get it replaced sooner rather than later. You don't want it breaking th in there and blocking the pipe

Thanks for the replies so far, this forum is handy.

I can't imagine how bad the underneath of the car would deteriorate from salt :/

Yeah by the looks of it the old genuine cat has been cut out and a new aftermarket one has been welded in. Although from looking at the cat up close and tapping on it, it seems to be in good condition, however I'm not sure what it is like inside.

I'm going to Peugeot today to collect some badges, so I will get a price on a genuine center section. Mine is definitely stuffed.
