I've got one aswell and have seen 2 fitted in person. To be honest although i agree that we should have been told about the modifications that have to be made, its not that big of a deal. There has been a few thread discussing fitment of the zisco inlet, so a bit of research would have went a long way. I always have a look for tips etc whenever im fitting new parts to save me running into problems. Also for the price and performance gains, aswell as aesthetics its not that much of a hassle.
