I have been told by someone that by restricting the exhaust system to control the noise output on a bike will in turn overheat the motor and destroy it.. Yes/no??

I have also been told by someone else that by creating more heat will help with the combustion of the air/fuel and in turn create more power..

I realise it's probably a fine line between the two.. Restrict it to much and you'll lose power.. But if it's restricted just enough to get under a certain noise limit then, then it's not being restricted *** all, I'm only talking about knocking 5-8 db's out of the bike..

Induction noise would also be a contributing factor to the noise output so a makeshift airbox should help.. Bikes allready run foam filters alone..

What about heat wrap.. Is it a bad idea to wrap a 2T exhaust in heat wrap??
As there'd be a certain portion of the noise coming from the expansion chamber's..

The type of bikes I am talking about are Moriwaki 80's, Metrakit 80's and the like, jnr road race bikes or Bucket bikes to us old folks..
