Peugeot 206 Loud Knocking when engine struggles or pulls away

[ScottishPeugeot]

Hello,I was looking for some advice on a problem I’ve got with my 206 1.4 HDI,it’s done 48K miles and recently I got the exhaust replaced and noticed after it was fitted that when I pulled away or the car slightly struggled there was a loud metallic banging?I was wondering how would I fix this and what is the banging noise on the exhaust?

I would take it back to the place who 'fitted' your exhaust, as if the noise has started after its replacement, then it is very likely they have either not fitted it correctly and it is knocking against another part of the underside, or it's not a good copy of the original - either way, once it's up on a post and the engine is stopped or revved, the noise should be able to be replicated or isolated, if it is indeed the exhaust.
