Hi all,

After changing the timing belt (which went successfully), I noticed a rattle under the car under accelerating. Took it to Halfords for an exhaust check and they found that the exhaust had a hole in it. They said this was not the cause of the rattle but needed fixing (fair enough).

I then checked under the car myself and noticed that the bracket for the catalytic converter had broken (presumably due to rust like the hole in the exhaust).

So now I plan to change the whole exhaust from the cat and my question is:
Are there any pitfalls when changing it?
Is it just a case of unbolting wherever and removing it from the hangers (or however it is attached to the bottom of the car)?

I have tried to look for videos but couldn't find any for the C3.

TIA

Hi Marcianyn

The original factory systems are fitted in one piece. Where as the aftermarket exhausts are supplied in two parts.

If you have the original factory system fitted, then one of these exhaust chain cutters (new, ebay) are a real help to remove the factory part.

Other than that, inspect the rubbers and hangers and change any that don't look their best and I don't think you will have any problems other than access.

It is 100x easier to do an exhaust on the vehicle lift than on axle stands.

Rust on one of the brackets is extremely common on C3s and the equivalent Peugeots. All it needs is a helpful company to weld it. I am a regular customer at a tyre fitters, and they did mine gratis.

Right, parts are ordered. :)

Will have a stab on the weekend at replacing the exhaust and will update here after.

Quick update on progress:

One of the old bolts used to clamp down the cat to the middle silencer snapped and the ECP bolt does not fit through the hole on the cat. Plus can't get all the hangers to fit perfectly due to some more snapped bolts on the car itself...

All in all can't get the exhaust to align and fit perfectly on my drive.

Taking it to a garage tomorrow to get the last bits finalised as I have thrown in the towel on this one

Quick question:

I forgot to buy the gasket for in between the silencer and the catalytic converter as ECP does not sell the part in question (GMG42). I found a number of versions on both ebay and amazon and I am not sure which one will fit.
Can anyone suggest which one to get as the car is a bit noisier and I am sure it is not sealing 100% either?

Thanks
