There is plenty of Alfas on youtube with various exhausts fitted,
but today I came across this one from Hong Kong, its probably
the fiercest sounding I've heard.
The poster has an older post with the same exhaust but the
word 'front' added, does this mean he has had an extra addition
to the exhaust since his first post?
(As the last comment suggests)
This maybe should have been posted in the 156 GTA Section but
then I'm sure some people would have missed out on hearing it.
