I have plenty of videos of my dynoport pipe on my quad on youtube. They big volume pipe is a great pipe. Dynoport also makes a mid-top pipe. I am running a ftz pipe and silencer on my ice quad and let me tell you it's far from fuckin crumby dude. It pulls hard real hard. Paul turner mid pipe is an option fr moto. CT makes a pipe for lts. And the psi is a great pipe also comes on hard and quick. There is lots of things that need to be setup along with the pipe. Can't forget about lrd also. Another strong pipe basically the same as the dynoport big volume. Again so many variables go into the pipe/motor setup to make it work to its full potential. Fmf or the turner mid or psi may be good choices for moto but I like th dynoport big volume.
