I have a used Coffman's Shorty exhaust that came on my used 2012 CBR250R when I bought it a year and a half ago. It has the blue anodized tip with a black body. I wanted to switch exhaust, so I installed a new one and now have this for sale.

It's in good used condition. It does not have a clamp (easy to find anywhere & very cheap), because the bolt snapped when I was removing it from my CBR, so you'd have to get your own clamp to bolt it on.
I had to dremmel the small rivet head off of the area where it attached to the pipe, so there's reasonably small scuffing in that area,
Feel free to contact me with any questions. If this post is up, the exhaust can is still for sale.
I will not ship outside the continental U.S.
Price including shipping is $125 to anyone in the U.S.
