only just seen this post!offshore at the moment and just gotten internet acces! i sold ryan the decat pipe and it came off a smashed wr1 which had a full stainless system on it! wuz from bhp developments can confirm this as it was stripped at his house! have you managed to get a measurment of the centre section? also could it be that there are different system between bug eye,blob eye? as i know the hawk eyes are different to blob eyes?
