My issues are similar to ///M1, the clearance side to side and upwards are both issues. I took it to a company that manufactures exhausts on Friday. They were not impressed! Titanium does not respond to 'tweaks' well and they would not do this. The nature of the joints make it difficult to adjust. My installation results in the right side tail pipes protruding approx 10 mm more than the left, this can be seen across the whole of the rear box when viewed from underneath. I have been given an email address at Akrapovic. I received a response earlier in the week along the lines of sorry you are having problems, all of our other customers are happy. There was also a promise to look in to it with the R&D department, I've not heard anything further as yet.
I would encourage all others with issues to raise this with the contact I have been given, Reven Mitja in the marketing department
