Drill some holes into your pipe - then it will be louder.  Do the same mod that is suggested for stock pipes.

Cool! I would swear that was a Ducati.

Which system is that?  A straight 2:2 or a 2:1:2?

It sounds cool, it looks cool, and the performance at mid RPMs is much
better too. How about + 6 horsepower at 6000 RPMs (+20% torque)?

Twin cylinders with a 180 degree cranckshaft work better
with dual exhaust architectures (see Kawasaki's GPZ500
versus ER5: same engine, but 2-(1?)-2 versus 2-1: worst
global performance in the latter one!).

how much did the whole mod cost?

Mine costed the equivalent sum of about 600 dolars/euros,
a couple of years ago. A local shop (not fancy brands!) here
in Lisbon did the job. I gess the difficult part is to make the
headers: they're made of several pieces (inox can't be bent),
soldered together and polished; the bike was in the shop for
a couple of days (http://www.pulsar.pt/).

I think so also, since the stock Suzuki system easily gets rust in the
headers (and eventually the pipe will die also). My headers are inox
(lifetime warranty) and the pipes can be dismantled to replace the
interior tube (an iron piece) or the noise absorber material.

Now the bad things:

(i) inox gets EXTREMELY hot! beware of your fingers in the headers...
if it were another engine and not the bullet-proof GS500 engine, I also
would be worried about the impact in the running temperature of the
engine's head (the heat is extracted from the exhaust gases, which
collects in the header and than goes to the head; inox "grabs" more
heat than regular iron); also, if mud is allowed to contact the inox
when hot, then it reacts and leaves spots; that is, for a shinny look,
(i) don't ride in rain or (ii) "clean" it regularly (i.e. acid treatment,
plus a regular polish!);

(ii) bad things about the pipes: I hit the ground 2 times at low speeds...
the pipes didn't break, of course, but the outer carbon shells become
scratched and dented. If the outer shells were of metal, a good polish
would solve the problem. In my case, I had to buy new external carbon
fiber shells - which are expensive, about 100 dolars/euros.

Best regards.
