I am going to look into it, but I have already voiced my concerns about the tails. I do have other options for tails but I am very fond of these. Janspeed have told me that the tails will not be an issue against the plastic diffuser.
At the end of the day guys they have been producing systems for 30 odd years so they obviously know their stuff, Also this system is being made specifically for the 197, this will be purchased dominatley by people from these websites, if it was to c**k something up I would be the first to complain on every clio forum I am a member of, I don't think they would damage their reputation by telling me it will be perfect, when in fact they are not sure. I am more than sure they have produced systems like this in the past for similar scenario cars and thought about these potential issues on numerous occassions. I can't see a professional exhaust production company making a pigs ear of it.
