Other than OEM exhaust question

[chuter]

The right side muffler finally gave out on my so a replacement is needed. If I don't go with a NOS or "used but nice" replacement for it and the left side; what are your recommendations for new pipes. I only need the pipes aft of the joint below the brake lever or shifter lever.

I saw some discussion on the MAC slip on mufflers. Any further input on them as far as success with them? Part numbers for an 80CB650? Thanks.

what you have now? I have 3 right side 4-4 if you can use that.
