Omega Exhausts - Snakey
Alas, I am one of the unlucky owners of a 2.0 Omega and have
just been told that a pinhole in the front downpipe of the
exhaust will mean replacement of the cat as well (The two are
one if you see what I mean)

It seems a bit extreme to discard the cat for a holed pipe, has anyone out there had a similar problem? Or can anyone recommend
a cheaper solution than replacing the £250+ cat!

I've tried exhaust repair paste etc several times in the past and it only seems to last a month or two. And the section of
pipe thats holed is 'ribbed' which makes for a really awkward
repair.

Time to learn how to weld I think!

Go and get it welded and fix the problem properly.

If the corrosion is very local, you might be able to drill the pinhole and block it with bolt/nut/washer.

If you can't get to the inside of the pipe to do this, you could try using a heavy gauge self-tapping screw instead. In this case, you could open up the hole using a round taper punch so as to form a wall for the screw to bite in to.
