his pipes are metal and only got like 2-4 bits of of silcone at bits!
if want me to ask him anything abt it let me knw and i will ask um! he works a mechanic for vw so dont worry lol
pictures and prices would be good
they only do hard pipes dont they? they might have revised the pipe design to make it fit without modification 
You'd hope by now they would have sorted the problems......
