CBR250RR Screaming Demon Exhaust

This is one of the exhausts made by Screaming Demon for the CBR250RR. Nothing has been done to my bike apart from this exhaust. Edit from 9/July/2012: I’ve had people ask where I got this from. I bought it online and thats about it. I did a search and found this mob as the exhaust for sale (I think it may be a little different as it says it’s a shorty)
