For starters the as compared to the original exhaust the Dansk stuff is
cheap crap. Thinner tube, thinner flanges, and metal that rusts much quicker
than real OEM stuff. Unfortunately the good stuff is almost extinct even for
the 2.1L and if you do find it just bring money.
As for differences the 2.1 is physically more stout but to do it right the
engine carrier has to be changed to take the muffler supports. The muffler
is larger in diameter also. There is more room near the oil filter to allow
for the 2.1 oil cooler.

Ok everybody - its time we tried to replace the tire thread with a new one -
I own an '85 with a 1.9 WBX. I put stock exhaust systems on 3 times in 10
years, then put on an S & S header. It also lasted about three years, but
with less driving. ( Michigan winters, see.) The first, and main point of
failure on the
1.9 system was the wretched two-into-one join at the collector. Each of the
three systems that I have had fail went there first. By a noticeable
stretch.
These were not cheepie repro, but real Dansk items.
When I look at the design of the 2.1 system, I see that this weak spot has
been replaced with a very different design, using a casting in that
particular weak spot. (As an aside, I also noticed the design of the 2.1 1 -
3 and 2 - 4 headers flanges at the collector end was also changed, to keep
you from any partial updates to your exhaust. Grrrrr....)
And I am also ignoring cat converters and mufflers. I put my own mufflers
on, thank you very much, and they aren't VW standard.
My simplistic question, attempting to ignore as many extraneous variables as
possible is:
Which exhaust design is better? 1.9 Or 2.1? Pros and cons are what I mean.
The stainless issue is also not to be considered here, before you even
mention it.
Better breathing?
Longer lasting?
Stronger?
