Murcielago Tubi?

[Squirrel Nutkins]

My boss has a Murcielago at the moment and wants to add a sports exhaust. I have heard that Tubi are now making one but wonder if there are warranty issues or emission problems with it? Anyone that has it already, what kind of power increases can we expect from it?

Also will the ECU need to be re-mapped and if so anyone now the best people do do this?

Any help would be great!
