As above mate, I'd definitely push them in a lot further, I went as far back with mine as I could (until the clamps hit the bend in the exhaust). Looks much better then.
iv pushed mine back and they look lot better. thinking of gettin new exhaust now because im missing the sporty noise that i got from me fiesta st magnex system.
rev it hard & often, switch off the radio too
i was disappointed by the exhaust note at first until id done 1000 miles, it opened up nicely now i cant stop listening to it i think its perfect, with the windows up & radio off you can feel the sound come from the manifold down out the back rather than just a noisy back blaring away
Yes, would agree with the others here and say they need pushing towards the front of the car more. I've got the clamp on mine sitting almost on the bend of the exhaust.
