The muffler has two straight through perforated pipes. Tale a long stick and put it down the pipe to convince yourself. The goat bladder, unless it's got a catalytic converter in it, has two perforated pipes coming in, with a heat shield on the left side. The pipe coming out is straight through. The biggest muffler effect is with the intake. The small left side air filter, the restricted cross over duct between the cylinders are there to further muffle the sound by minimizing the amount of air that can reach the engine. Take the R/s cover off and take it out for a ride. You will be surprised at how much louder it is...If you "marble" the AIR valve intake, that, too will increase the total sound output.

I've spoken to the only big accessories and parts importer in the UK just now. There are no exhaust systems anywhere in the UK or USA that they are aware of. Apparently because of the age of the bike, non are left. I was hoping to put Vance & Hines or Cobra on - it currently has stock exhaust. So the dealer I bought it from had a look and said the baffles cant be drilled out of the stock exhaust.
Any ideas fellas? I cannot stand the choked sound of stock pipes. Do you know of a shop selling new complete system?
Or do you know if the stock exhaust can be modified. Thanks in advance.
