After researching some options for exhaust on the evo, I came to the conclusion that I don't actually like any of them. The termis are crazy expensive and I still don't actually like them.
My main goal is aesthetics, weight, and cat-delete.
Doing some measuring the outlet on the evo mid pipe is 60mm with the slipon outlet measuring 50mm. I searched around other bike models non-Ducati to see if any other models used a pipe that gigantic.
The bmw s1000rr uses a very similar mounting design as well as location. Slip on inlet is 60mm and outlet is 50mm. The idea is to modify the pipe for the bmw to fit the monster. Specifically the bmw uses a cat outside of the silencer so all silencers available for the s1000 will for sure not use a catalytic converter.
This is the pipe I chose.

Here is the routing and location for the evo

And routing for the bmw

One it gets here I can get to work on see what kind of bends or resizing pipes will need in order to make it fit. But it will take some work.
