I need some advise. I have the stock velocity stacks in my airbox but I'm curious what would happen if I took them completely out or cut them off? Has anyone done this modification yet? If so please let me know what happened good or bad!

I think you would screw up the works. I have heard of changing the location of them in the air box or of some sort of height modification, but I really don't know.

If memory serves, they are there to clean up the way the air enters the head. It has something to do with the smooth path of entry.

go to factorypro.com for 80mm velocity stacks.
