General cost of replacement parts?

[jimsym]

Hi guys,

Ive got my eye on a zxr400 that needs a new exhaust. A scour of ebay, and the majority of exhausts seem to be in the £200 price bracket and aimed at boy racers.

Do 'normal' pattern parts compatible with the zxr400 exist (end cans specifically)? And if so, where are they to be found?
