Exhaust Options

My '76 Kz900 currently has a 4-to-2 exhaust on it. That's the exhaust I got it with oh so many years ago. I really like the balanced look of the dual sided exhaust, but I recently found a leak in the right side silencer. I've never worked with motorcycle exhausts before except to take them off and put them back on as a whole.

Is it possible to replace the silencers without buying a whole new system? I don't really want to blow the money on a whole new system, but the baffles are just about shot in this system too.

Photos of exhaust are attached.

If you have access to welding equipment, you could make your own baffle.

On my '78 KZ1000, my right side baffle corroded and finally fell out. So I made a replacement baffle using a 1" x 12" pipe and a couple large fender washers. Worked great. Sounds great.
