Anyone swap out thier V-Stacks and dyno it??? I've seen stories where the dyno charts show an in crease of 4-7 ture HP. And the mod is pretty cheap..it's small plastic but it's like 400 or so..it's expensive cuz of the R&D put into it

No but did consider lookin into it. ya can get them included in one of the HRC kits but can`t see there prices being reasonable.

Ordered a set up direct from Factory Pro this week will be here in 2 weeks and I'll let you know the HP improvement but they were $199 for a set for a 929 not $400 so that didn't seem to bad.

That's a lotta $$ for just a few extra ponies. Are those gains with a full exhaust or slip on? I remember looking into different stacks for another bike and the top end gains were at the expense of some mid range power -- don't know if this holds true for the Hondas. It'll be interesting to see how the dyno runs go.
