Do you really want that carbon monoxide exiting there?

It is supposed to be less expensive than a replacement from VW.

Why not keep the car to keep the air clean?  What year is your car?  One of
the Scirocco manifolds (1984 for example is supposed to be one of the most
restrictive.  If you have this one, the manifold and down pile from
Techtonics will help you.)

The stock manifold is a cast iron unit.  Headers are usually made up of 4
individual tubes, one coming from each exhaust port.  According to the
Techtonic literaure (which you should get immediately to help you decide
which parts will help you and which parts are sold on hype alone) a header
will give marginally more power than a good stock header.  The downside is
that they are a bit louder, are thiner and therefore tend to crack or rust
and need more frequent replacement and some say they let more heat pass into
the car interior, a comfort item.  TT doesn't think the headers are really
worth it, unless you are racing and need that little extra bit of power.
