Graves velocity stack testing

Watch video or scroll down for dyno run. All results shown are with my flash adjusted for each set up.

The below dyno run is the graves low mount with the stock velocity stacks vs graves velocity stacks

To verify the results I was able to achieve with the graves velocity stacks, the below dyno run is the graves header with the stock canister with the only change being the graves velocity stacks vs the stock velocity stacks

I tested running 4 of the short stacks vs the normal configuration and I do no recommend running 4 short stacks
