What do you run for short, equal length velocity stacks?

Have a Harley, spent lots of money on it, thought I had a fast motorcycle, bought a Busa, realized all I had was a fast Harley, not a fast motorcycle!

Yes that is what I use.
Karl was using some stacks from John Hartley but I can't speak to what length they were or price.

All of Karl's stuff was Gen1. I run John's stuff on my bikes. Really nice pieces. I did not check if he makes anything for Gen 2s. Hartleys stuff is not really expensive, but lots more than the rubber OEM ones.

I was using the stacks off of a 2007-8 GSXR 750.  All short.

I think that is what Schnitz sells for short stacks on Gen2 Busa. I have ordered a set.
