Slip-ons for the Streetfighter...

[Speed 3 Pilot]

Also looking at the QDs, MotoWheels had this comment about their slip-ons>>

The owner said his slip-ons will work with his dual high pipes and a new single sided high pipe mid pipe that he was working on. If you decide you want to run dual high pipes later- you only need to purchase the pipes. If he goes into production with higher shot gun style single sided pipes, you will only need the mid pipe.
