ahh, I always like your detail-ness and refined explanation. I know how to do, but explanation wise real sux 
the exit hole is big enough for 135cc.
The original design with disconnected pipe means... the gas must fill the tube first before the gas go out via a small hole. low speed ok, as that big piece of tube serve as a gas collector, but at high rpm, everything farked up.
in my opinion, we just need to make a direct connect from the 'honeycomb' pipe to the exit hole. No guarantee 100% is the perfect setting, but at least it will be much better.
Paiseh paiseh. Thanks.the exit hole is big enough for 135cc.

IMHO, this is a stock pipe, it's got no value today, but it shall be priceless next time.
From the looks of it, it shall last for a very long time without need for service, except the exterior need spray painting maintenance against rust.
With the money spent to open it up, I'd rather get a new aftermarket one. Spray it matte black, to look less problem inviting as possible.
My idea to mod it will be similar like yours, but the honeycomb will extend through the last 2~3 inches before exiting the exhaust chamber.
The whole length of the resonator, wrap with fibre and another layer of steel sheet, tie it up nicely and the pipe should be quite silent.

Car mia kat bawah cant see ma but for bike gai nia cut a few times whole pipe ada ''parut'' sakit hati lah
A good finishing job will do the trick. I like it matte black.This post has been edited by alexei: Aug 29 2010, 01:53 PM
