Hmmm, it can be done, and it can look quite clean too, not my sort of project though, did own a golf v6 4 motion not too long ago, and the v6 sound is quite something....petrol prices soon put a stop to that love affair..

Anyhow, back in 07 went to rsoc, think in Rockinham, not sure, took pics of this cab...
Can't help but think, there are much easier ways of getting the same power, but i am just going off topic...
Not really a fan of the colour but the rear spoiler has got to be a first, worth more than the cab lol
