i've had 4 of the most popular right bends made...
Trinity/CT multi cone, an F7, an LRD adjustable and a Dyno Port.
here's my findings, all run/tested on my heavily modded white bike, see my sig for details
and on my piped/filtered/vf3/stock carb, non ported black bike
the Trinity pulls the longest (highest rpms) of all the right bends, the F7 and LRD were a close second
i didn't give the DP a very long chance as it was the only one asking for leaner jetting.
i didn't like it on either bike.
the Trinity is now back on my white bike, prolly forever.
best pipe of all i've tried for my mods and riding style.
some seem to think the high rpm pipes are more for open area's ?
they've obviously not figured out how to stay in the rpm range the pipe makes power ?
i ride tight mountain trails/roads and rarely see 5th/6th gear.
i now have what most consider the top left bend.. Toomey
on the black bike.
it hits hard at about 1/4-1/3rd throttle, but drops off the power way before any of the right bends.
