All,
When I bought my GS originally it had a loud exhaust system and I got the car dealer to put the original standard one on instead and they knew a buyer for the loud exhaust, anyway 18 months later I decided to collect the loud exhaust since they had not sold it, but I reckon they gave me the wrong exhaust, it may even be from a ferrari or Lamborghini.
Hence why I have the exhaust.
Last week I took the exhaust to the garage that I purchased my GS - Sydney Road and Track, all they did was to take a photo and they would get back to me. They did not get back to me even after I left 2 follow up messages with them.
