Yep it's a bit involved to get it out, I found it easier to remove the downpipes and cut from the bottom. The cut is at the 90 degree turn before the turbo, I used a small hacksaw blade holder to do it but an oscillating multitool would make things a snap.
I've also see DIY's mentioning removing the intake manifold to get it out but I'm not sure how well that method works.
A good DIY is here:
