1983 Suzuki GS650 exhaust avice needed.
 

This bike has an aftermarket exhaust on it that has 4 tubes going into one muffler. It is way too load. I would like it to be very quiet. I don't want to hear it at all (ok not really possible but that is the direction I want to go). It looks as if the muffler is clamped on so I was wondering what muffler should I get to make this bike whisper quiet?

Your recommendations would be appreciated.
Thank you
Bill

Hello? Anyone? I am attaching a picture of the muffler. I took it off the bike and it is empty. Can new guts be put in this type of muffler, or do I need to replace it? Your help would be appreciated. Thank you
