C4 Exhaust

[alloywheel38]

My 2litre C4 VTS has had new exhaust fitted but it still sounds as if its blowing the front pipe (by the flexie) has been replaced twice any ideas anyone plus can u fit a USB port into the sound system??

Which engine is it - petrol or diesel and does it have a dpf if diesel ?

 

Are you sure it is the exhaust and not a manifold gasket or a fuel injector/cylinder head seal that is blowing ?

 

Whenever I have replaced exhausts I use a bit of exhaust paste on the joints so they seal, just relying on the metal to metal joint can leave small gaps.
