Muffler packing on estoril

I noticed the muffler portion of my estoril was loose the other day, and I removed it to see that was inside. I got to wondering, what advantage or disadvantage would there be to removing the fiberglass packing in the muffler. I wouldn't mind having a louder pipe (I'm a firm believer in being heard before being seen), but would it negatively affect performance?

loud pipes annoy neighbors. You'd be better off hacking open your expansion chamber and pulling out the little restrictor plate.

You need a certain abount of backpressure for the bike to run. If you want a loud pipe, try the tecno hunter. My drug addict neighbors hate me :)
