Conwy, I have questions:

1. Where did you have your pipes installed and did you buy them there or somewhere else?
2. Is the AI that pipe that runs parallel to the spark plug? What is it's purpose and why did you remove it?
3. What is a Unifilter and why is it desirable? What is involved in the installation?
4. Have your pipes blued and if so, what if anything do you do to remedy that?
