Hello from Canada

Greetings all, noticed there weren't many black ones here and thought I'd share a picture 😀.

I'm looking at exhaust systems on ebay from zx25r(r)'s and I was wondering if they all fit on our bikes?
This is a commuter bike and I I'm not looking to spend big money therefore I'm simply looking at removing the exhaust restrictions and giving it a bit more sound.
The ko brand looks quite decent but they told me it doesn't fit our bikes...
Anyways, thanx in advance and happy riding!
