The C5 I saw at the BMAD bike show last week had the curved exhaust, however not sure how much extra it was.
Unlike the pillion it had, the exhaust looked pretty nice, still not sure which I prefer but def nice to look at.
As for emissions laws, are they EVER intelligent and fair? Environmental and emissions requirements are money making instruments... The amount of lunacy involved is incredible. They'll make life impossible for a small importer selling very economical, high millage vehicles hell, and then the fat cats can dump thousands of tonnes of crap into the environment without penalty.
They're trying to get water fluoridation into the UK, a waste product from aluminum production linked to A.D.D in children and increased susceptibility to many forms of cancer, yet you can no longer buy vitamins of any strength in the EU, it's all money.
