hi. a question if you mount the two brothers slip on then you need a Power Commander v or can you drive like that.

2 broth amazing sound.great video and great sound

Have you installed a DynoJet PowerCommander on a ZForce 800 yet? We've already put one of these two brothers on our Demo unit, and are thinking about putting on the DynoJet as well. Also, do you know of any clutching parts, like weights/rollers/springs for these?

Its actually the exhaust shield i found out that is vibrating on the spring... Just bend it a tad bid and you'll be golden 👍
