They have now completed testing and the the price for the cat back system is £838.88 inc vat and fitting would take an hour which would be an additional £76.38 inc vat.
I need to hear one before i shell out for it, i have heard story's that the system doesn't actually add that much in way of sound.
So hesitant at the moment,
oh, this is in the UK - if anyone is interested i have contact for a top notch garage that will fit them
