Here we have a set of pipes for a Laverda 750. It came along with a 68' 750 GT basket case I bought several years ago.  They are chrome plated pipes and as you can see in the pictures someone welded crossover joints.  I am not sure why someone would do this to a perfect set of pipes.  No dents or rust.  They have 22747 engraved on the end where they meet the mufflers.
