The original exhaust systems (including the oxygen sensors) appear to be trouble-free on these cars. After 7 or 8 years, the rear exhaust box may need replacing and this is a straightforward job for the local exhaust specialist.
More recently, I have needed to replace the 16 year old centre exhaust on one car - check if you need a fitting kit 1797.74 first, as it includes a special "slippery" gasket. If the old one is refitted, you may get odd squeaking noises as the exhaust tries to flex.

Rear exhaust hanger
These can rust out after a long time - but can be replaced - see ebay advert or search for "Peugeot 1007 rear silencer exhaust strap". It would be a good idea to spray with a can of heat-resistant spray paint as the sides may not be treated so it could start corroding again - - - -
Alternatively, this is an aftermarket rear exhaust - the hanger is welded directly on to silencer.
No noticeable increase in sound levels - works well and cheaper! Fitted June 2014 and still OK seven years on
Lambda O2 Sensors
There are two on each petrol engine - see drawing
Catalytic Converters
The average age of catalytic convertor is 10 years, what would be the most accurate way to isolate a faulty or partially blocked one in a 1007?
I've not heard of any needing changing on the petrol models so far - they do seem to go on and on. Unless the engine light is on, leave well alone.
If the engine light is on - then
- Is it misfiring? If so then plugs; maybe coil pack.
- If it hesitates at low revs - then change MAF and clean butterfly area
- If short of power; check air filter (it may be clogged or worse, got wet somehow)
- Quite often the engine management light can go out after a motorway blast to clean everything out and/or put a heavy dose of fuel system cleaner in the tank.
Only once these are all checked and cleared, then look to the O2 sensors and/or catalytic converter
My view only - others may have better solutions.
