Quite possibly a daft exhaust question?

Ok,
    i've decided a louder can is in order, but i'm far too tight to replace the standard one given it's in good shape & i've a long list of other "to do's"
 
I'm guessing there's some wadding put in there by Mr Yamaha & co.
My question being~ is it possible to remove some of it for a more sporting exhaust note & if so how?

I would imagine your back pressure would be affected, and there's no guessing what sound it would make?

years ago before can`s were affordably we used to weld a drill bit to a bit of threaded bar and drill the inard`s out took a while an a bit fidly but worked well and you get all the gain of a free flow if done right

Ok, thanks for the replies folks.
 
I do have a spare can to experiment with, just trying to get a handle on what exactly's inside.

Not exactly bike related, or directly relevant, but a few years ago I was a tech inspector for the Legends race cars, which ran the 1200cc engines, with a Micron can.
One race meet we picked up a different exhaust note on one of the cars, so pulled the exhaust apart to compare with a brand new item.  The new one had what I believe to be some form of fibre glass matting, whereas the 'revised' version was packed with wire wool. 

The owner, and modifier of this exhaust is also the owner of a well known aftermarket stainless steel exhaust company, so I guess he had some idea of what he was doing...

I've had occasion to open up a couple of OE silencers and found them to have two or three chambers with a number of 1" tubes as interconnectors. I've not dismantled an original Fazer exhaust though, so will be interested to hear what you find.
Other than the one on a little Yamaha 2-stroke I used for a while, the only silencers I've seen that employ a central perforated tube surrounded by an absorbent wadding have been after-market ones.
I suspect that the noise and heat that glass fibre wadding is subjected to causes it to slowly disintegrate and blow out with the exhaust gases anyway.

anyone tried the Fuel brand end cans?
 
They look pretty neat, seem to have a good write up and are reasonable priced.

Got a fuel can on my FZS600 and it provides a great sounds....overrun is fantastic! It's loud enough when you want it to be but you can settle it down so it's not annoying when you just want to ride in a more relaxed manner.....passes the MOT without the baffle each time too!

Sounds like just the job!
