Question on exhaust set up on Indian bikes

First off, mods - could you please merge this with the previous "Has anyone fitted a 130 rear tire on a Hero Honda?" thread? I went there to edit the title, but it doesn't show an option for me to edit my post.

Here's my question: My Beemer and pretty much every mosicle I have worked on (includes Ninjas, Triumphs and some Italians) has a 3 piece exhaust set up. Header pipe, mid pipe (usually three quarter inch diameter or 1 inch in some cases) and the exhaust cannister. This allows flexibility in mixing and matching and easy removal of any of the pieces. I noticed on the Karizma that its all welded together as one whole piece ?!?! I mean, how the heck is one supposed to trouble shoot anything if I have to cut it open and weld it back??

I am actually trouble shooting a rather loud whispering/whistling noise from the exhaust while decelerating or letting go of throttle. I took off the heat shield to make sure its not a vibration related issue and its not. I can't go any further because the damn thing is fused as one piece.
  1. Has anyone seen this noise issue before?
  2. Do Indian bikes' exhausts have fiberglass muffler packing inside? Sometimes, the mufflers just need to be repacked.
  3. Do Indian bikes' exhausts have removable baffles inside? Sometimes, the baffles rattle lose causing clanging and other noises. They may need to be refitted with some antisieze.
  4. Is there any way to take apart the exhaust without cutting/welding? The techs at the local dealership aren't too bright. They are saying the exhaust is a use and throw set up and a new one is ~6k rupees. I find this hard to believe in a country like India where nearly everything can be fixed.
As always, your thoughts are appreciated. Thanks!

Some bikes do like the Pulsars. In the case of Karizma i think it's al baffles inside and no glass pack.

No.

Not any that i know of. You can take out the golden shall. That's all.

Probably no one would ever replace the muffler in the lifetime of their vehicles unless it's beyond use.
Btw is that hissing noise only heard while decelarating? Did you check the pulse air pump? Intake side everything okay?
