I think Tom has this kit or similar. Although he has spent some wise money and had the whole pipework re-worked to be more efficient

Not sure if he ran it before having it re-worked or whether it was fitted and done at the same time
 
Toms is similar shape but much better I think and he has a passat intake manifold so it goes down the other side of the engine.

If you look on Briskoda in the group buy section there's lots of comments and stuff
