SGTi and Putra soundproofing

[JohnFrusciante]

Hi guys!
I would like to know what kind of soundproofing material that proton
put into SGTi and proton putra? can i buy the whole set from proton
or is there any spare part shoip that sell those thing? I mean...
the exact same thing.

I'm driving satria 1.3, seems that my frens gti with straight piping
and N1 type muffler feels more comfortable and the sound from
muffler is dampened at pretty adequate level(for me), and the
road noise is almost not audible, if compared to my satria.

I've been trying to use superlons and bitumen sheets but the road
noise still manage to intrude the cabin.

or,

izzit because of the chassis?

pls help..

thanks in advance
