Had a cruise to bathurst with the boy today and on the way there the vortex generator flew off!!

We added an extra strip of double sided tape and it still it managed to blow off.

Anyone have any suggestions on what should have been done to prevent this from happening?

Had mine done at Castle Hill exhaust, they supplied and fitted (welded) for $50, done a damn good job....highly recommended
