WTB one or two Cooper-style quiet pipes for 11cc motor

[JimZaremski]

Got a few engines which run great with these pipes (CMB .67 HR and MAC .67,) unfortunately a loose mount means one of mine ended up in 30 ft. of water Looking to buy a pipe or two of the Cooper quiet style. I've tried a Macs "muffled" pipe and it's 1) still a bit loud for my liking, 2) sticks out too far from the hull, and 3) tends to cause me to pop glow plugs.

Thank you.

I have a black QP CMB .67 pipe that's been well used for $30 shipped. Still works fine.
