you can use your OEM k03 pipes for free...ive done it before...hack up the ends where they bolt to the turbo inlet and get a 2" (i think it was 2") coupler and clamp it down to the turbo...easy and almost free
I will give it a try. From my 1.8T experience (ghetto job as well), the biggest issue is the relatively short 'tube' on the intake of the compressor housing to get a good, firm clamp seat on.
I will check the diamters involved (K04 inlet OD, stock pipe OD) and see if I have a suitable coupler.
