It depends what you want. I wanted a stainless steel system, and got
it (with fitting) from http://www.racecar.co.uk/quicksilver/. They
took a long time to fit it, making sure it was just right. Its a bit
noisier than the original, sort of throaty burble at low revs. But
it should last.

I haven't needed to buy anything else yet.
