I did a search and couldnt really find anything. So any and all input would be awsome. I am looking at getting some Factory Pro Velocity Stacks. I was wondering if anyone had these, if so do u like them. And is there any other brand that you would go with instead. THanks alot

Don't. They operate great in a very narrow RPM range depending on the length. Outside that RPM range, they run like crapola.

Anyone Else???
