So, my T has a Scorpion exhaust which was fitted by a previous owner in 2013, and I'm pretty sure that the weld has cracked between the centre silencer and the pipe. I noticed that Scorpion have updated the design of the centre section to include a flexi joint, and reduce the risk of cracking. So I was considering buying a new Scorpion centre section and just replacing that. However it seems strange that Scorpion need to include a flexi joint whereas none of the other systems do, neither did the standard Renault one. I'm wondering whether this is just covering up poor fit or poor weld quality? I like the fact that the Scorpion is failrly quiet, and so an alternative option could be to get rid of the Scorpion and go for the KTR/Janspeed system instead, which I have read is also very quiet. Has anyone got recent experience of the KTR/Janspeed system, or any other quiet ones for that matter, which you'd recommend?
