well the majority of the specs that matter are in my signature - i just realised!
John, the gap is not huge but not small either - you get that with 15's! I'll have a dig through my pictures and see if I have a better one to show it, otehrwise Ill take another one of it when parents get back w/ digi cam.
I do have a video here that I got to share the exhaust note, once someone can host it for me I'll get a link to that too.
Any more info you want, just ask!
