To be honest pal im not sure what tracker it is. But living in Manchester i didn't want to take any chances! My friend is good pals with the local is clifford/tracker installer and got us a deal as he also had his s2000 done at the same time. Its a brand new tracker system, im sure its called smart track or something, not sure until i get back.
Like you said with the exhaust though, if i go for that one and its a little loud for me then i will be in touch at some point!
