For those who are interested I've now had the Remus axle back system fitted. Straight forward fit: stock off, Remus on in under an hour. Exhaust fitters said it was nice quality, manufactured well and easy job (couple of clamps). Sounds like it should have from factory imho now. Deeper tone and nice and raspy on shifts/under hard acceleration. Definitely get more feedback now.
Vid link below - mobile phone quality so a little tinnier than in person. Wouldn't usually revs the nuts off it like this either and personally think it sounds better in mid rev range anyway.
Thanks to metalgod for his write ups etc too. Helped me decide.
