Default Pre-Cat Manifold

anyone here using one?
i got one for free, but i need to cut off the cat and weld on a flange for my turbo. i don't have a welder, or a chop saw.
if anyone has done this how did you cut it?

i have one, i just didn't think that would cut it straight enough. should i cut it so the flange angles a bit away from the block? or will there be no clearance issues?
thanx

If it's one like the image above, just use a hacksaw and cutoff the cat. That's what I did with the one I used.
