Janspeed. According to kev, one of the best non chavvy systems for a 182. Fit spot on too. Milltek sound fine (even for me), but the fit was pony tbh
I also have never heard of a custom place make a decent quiet stainless system, ever. It WILL end in disaster imo!
It'll be the centre section, very common on the Magnex sytems. I had one on my old Cup which failed, so i ebayed it, cos i'm a c**t
