Hi All,
I've done a few modifications to my 21 Plate X3 30E.
Alloys, Body Kit, New Turbo etc... But the only thing that's eating away at me is the Exhaust sound.
I've gone from an M4 Comp which was aggressive sounding and loved it!...
To a very nippy Tank of an X3 but sounds like a mouse. I need a bit more of a beefy sound.
I'm not looking for a full exhaust, But one that sounds much better while having valves still.
I use the Electric/hybrid most of the time when driving with the family so when i'm on my own i want to enjoy it more. Sport mode and so on...

I live in the UK so only UK based suggestions please :)
