I heard a little blowing sound coming from the underneath near the centre of my car, which can only really mean one thing. So I got it up on the ramp and had a look over and confirmed a hole had appeared in the silencer on the mid-section of the Fujitsubo system.
Clearly its still a bit low for UK roads and speed bumps as you can see the scrape marks have worn away the thickness of the metal over time. I have the car booked in with Zorstec next Wednesday to make a up a whole new centre section pipe without the silencer this time, should sound pretty good I'm hoping!
