just had new mid section and backbox fitted to my mk2 clio 172 at ATS as the exhaust system on the car was knackered when a bought it 3 weks ago and wanted a quick fix with no hassle £300 later . seems really noisy and a constant creaking has started on idle like between the cat and the mid section. Is the standard system loud ??? as sounds kinda chavy at the moment not what i was after.
