Trying to find some threads where someone modified Termignoni shorty for the newer monsters or even Arrow Thunder shorty for MV Agusta Brutale. I love the way they look and sound. [thumbsup].
Here are some links to Youtube videos showing both exhausts and how they look on the S4R and MV and how I want my bike to exhaust to look.

the arrow can probably work somehow, but that termi shorty is specifically designed for the "udder" (catalytic converter) on the S4R.
