AU3 XR6 VCT exhaust question

[Matthew]

Hi i have recently purchased a series 3 XR6 and was just curious if the exhaust on it is standard or an aftermarket one. I havent seen many VCT XR6's so im not to sure what should be under there or how they should sound. Mine seems to have a deep sound to it at idle something i havent really heard from falcon 6 cylinders before, sounded like a video i saw of a VCT with a lukey exhaust fitted to it, it sounds awesome and has plenty of go particulary down low, im very happy with it just doesnt seem right but as i said before i havent been involved with the VCT before so its probaly how it is.
Id just like to know for sure what it is.

here are the pics













and this is the one that raised the most suspicion, towards the rear end of the exhaust is what looks to be a sticker of some sort you cant make out what it says as its worn off and all thats left is the marking of the sticker.





cheers
