TT 2" exhaust question

[schofiel@telusplanet.net (Curtis Schofield)]

Hello!

Hmm, On the TT site there appears to be a different version of the
exhaust system for up to 84.5 and after 84.5 Sciroccos (One with full 
size spare
and smaller tank, other with small spare and bigger tank)

Does anyone know the concrete difference between the two exhausts..
what would they have had to change to make them fit?

I'm asking since i have my eye on the TT exhaust for-sale on ebay..

Curtis..
