Folks I am planning on picking up a second hand Milltek downpipe at the weekend. The one pictured is for example. Where I have marked in red when I shine a light from my phone on it I can see the light on the other side? Is this correct? Should it not be completely sealed? It has 4 tack welds on one side but on the side where the gasket goes I can see the light coming through when I shine the light.
