Hi pbekkerh,

I bought some a couple of months back from:

http://www.mfactorywest.com/

I emailed TZmike@Mfactorywest.com.

Fantastic silencers. look & sound great, brilliant build quality and reasonably priced. I went for the 250mm.

If you have a look on the second page of the bike snaps mines headed up Mark's nsr

regards

Parky
