I recently purchased a new Delkevic exhaust for my bike. I'd read a few negative things about them online, but the cost of the silencer proved too much for me to resist.
I went for the 200mm Mini 8" silencer for my 1999 Kawasaki ER5 and the thing sounds amazing. I have to say, I am really impressed with the whole purchase. It arrived with no problems when expected, as described. In the box I got the silencer, link pipe, clamps, bracket and instructions.
I've got some before and after shots of the exhaust for you:

And two YouTube videos for you.

I recently sent them an email to say how ace I thought the exhaust was, and they sent me a free gift in the post!
If you're looking to get a new exhaust, I'd definitely recommend them. Especially seeing as they're a British company! Check out their range: http://www.delkevic.co.uk/
