I have a R56 cooper s and I have the JCW
cat back. Its still not loud enough for me :-/ I still have 5 months warranty on the car left also. I looked into a sports cat but they are quite pricy. So I then looked at decats but although they are cheap, there not legal really and I don't want fault codes coming up etc and because of my warranty i dont think i could get away with a decat. Can anyone help?
