RM270...?
i can install some sound proofing item for my car and prepare this much of $$$ for my next coming service

Added on September 27, 2011, 10:29 ami remember there is someone posted the sound proofing rubber for the door edge with some photo of 'Before' and 'After'... anyone here can give feedback on that? i'm now using stock rubber (FLX), and what i hear is :
5% people talking from outside
5% engine noise @ idle, 15% when cruising
10% wind sound when cruising @ 90km/h while, 15% @ 110km/h
40% motorcycle exhaust sound
do all those noise can be lower down after installing the sound proofing door rubber?
btw, the tyre noise is for sure we can't do any for it...

Wa, you are maths expert la, can figure out how many %...
This rubber can reduce 'some degree' of engine noise, road noise, wind noise and pass by vehicle noise.
My suggestion, just change it without much consideration needed, as RM150 is not really that expensive only, it will at least improve some rather than none.
If really want comparison, it is much more better than invest in some placebo effect item such as VS, grounding cable and different grade of engine oil, what you get is much more satisfaction.
