OK, here's the latest. Had to move the driving lights but not the indicators. As you can see, it's a close fit. The filter is a huge improvement and acceleration from 2500rpm is mind blowing. Even the exhaust note is deeper. Next I want to sit it in a bit further and fill in the gap with the top edge of a bear claw - I have one coming (thanks Anth).
Cobba mate, you were really onto something. The increase in power is quite remarkable and it sure is an attention grabber. Now for a decent exhaust header.........
