Not a complete stainless system, but its a stainless box - Kawasaki 98 ZX6R Ninja type box (stainless) - £20 from ebay including postage and a header from an aftermarket empi type 4 system (lines up perfectly with early T25 exhaust systems) - cost me £60. About to treat header to a blowtorch, burn off the paint and replace with EHT paint. I would imagine that any T25 that has an end fitting to the silencer box (early watercooled like mine doesn't - hence header pipe) could be adapted to take a stainless (road use only) bike box. What is harder to glean is the 3-bolt spacing as they vary from bike to bike and manufacturer to manufacturer but you can always get a plate made to take one 3-bolt spacing to another type:
There are also carbon-fibre ones around and even 'shorties' (cut down boxes) and there are loads and loads on ebay at under £40 (look for silencer cans). In time will have remaining bits of the system made up in stainless as I go but its a good start and still cheaper than a brand new tinny VW silencer on its own.
You can actually get virtually any 3-bolt cylindical silencer box from a bike to fit providing you pick a reasonably big un so as not to restrict gas flow (puch maxi not recommended!) - you just make an adaptor plate to suit (above) in the same way you have wheel adaptors - not hard to make to be honest. Alternatively I guess you could weld your own flange to any existing system but with future repairs in mind, an adaptor makes more sense.
GTI mad man is right, although not everyone can afford/justify £400-£500 on a system in this economic climate. if you fancy trying different configurations, this is another way to do it and its the ultimate in recycling - cheaper too
Hmmmm... I think this may well be a WIKI. I'd twigged this for a while but kept stum while I had the pick of ebay for possible boxes
