Topic: K7 750 stock mufflers

[Erny]

Based on my friend questions, just wonder if my stock mufflers are 100% original or PO drilled them - there are quite some holes, irregularly positioned, so looks like drilled?

Sound is good, just curious to know

[kmb69]

Definitely been drilled.

At least they don't look like this!.....

Are these yours you purchased recently? Looks something is missing, no?

No, these were how I purchased my 78 cb550k which has the same style seamless as the K7 & K8 750.

The PO had cut the ends out......sounded terrible!

This is how they look now...

Can you post pic of yours on K7/K8 to know how it should look like?

If it were me, I would fill those holes with JB Weld and paint them flat black.


I would make them quieter though

You better sell them to me

Thanks for the tip, I'll check that. they are in UK too, so maybe it could be cheaper if ordered via UK shop
