Hi all.

I have bought a 4-2-1 manifold from here for my 1.6 16v astra z16xe but it has no connection for the flange bit. as shown below. What can I do to connect it to a race pipe. I've seen this one on LMF http://www.lmfvauxhall.co.uk/store/p...at=1573&page=1

but only thing is I looked underneath my car and the centre pipe isnt straight when connecting to the manicat as show on the LMF website
