repost: performance exhaust for 80 Quattro???

[Tessie McMillan]

Reposting this question due to lack of interest. (I've received queries
from other listers asking for this info too, so apparently I'm not the
only one who wants to know!)

What is a good performance exhaust (cat-back) to put on an '88 80 Quattro?
Does the Stebro fit? What about Scorpion?

I'm in dire need of a new system -- I'm even wearing earplugs on my way to
work now! Also, I've been taking this car to the track, so I'd like a
more than an OEM exhaust.

Thanks!
