Velocity stacks

[mmdm4]

I saw someone makes velocity stacks with blue or red bands on them but I didn't get the info on where to purchase them. Any help would be appreciated. Thanks

If you are talking about the bands around the top, I use heat shrink tubing.  Cut it to size, put it on and heat it up and it looks great.  Different colors also.
