Two sets! Still in their packaging Scoot, my old man likes to remind me that his Bonnie in the 80's was louder. Straight-through, swept out exhausts. Had some family 'round who were saying you could hear him from the next town (5 miles out) Ooh.. Forgot I took that. It doesn't have the audio quality to show it off, though!
Sounds fabulous, but I think it might be running lean with those pipes, unless you've changed the fuelling of course.
