Leo Vince spare parts

I have a Leo Vince 4Road REF. 4012C - SUZUKI - AN 400 BURGMAN i.e. (2003/2005)

			- TYPE: BWwhich I think was bought from SIP. Sadly a few years later it has split the downpipe. Is it possible to buy just the downpipe? The silencer is in perfect condition so it seems a shame to have to buy the whole set.</p>
