Right, I have fitted my K&N filter panel, and de-restricted my airbox (really happy with the results so far), however, I attempted to fit my Vectra C pipe too and I just can't get it to all line up :s I have followed theguide, but to no avail. NOTE: I do have the adapter too.
Some pictures of your pipes may just be what I need, and a few tips. I know a lot of you have this mod too. Any help would be much appreciated. Thanks guys.
