Well, as it is said “all things eventually come to an end” and so it is with the production of the Sleeper Pipes. It has been a great run but after doing about one hundred and ten sleeper pipes over the last fourteen or so years the time has come to call an end to it.

The forum owes a HUGE THANK YOU to Dave Meis! When I first came up with the idea to remove and replace the baffles with a cone in the mufflers it was to fix the failing baffle on my CT3 muffler (which I fully documented in detail on "the other Yamaha forum" now gone). Dave was with me from the beginning and we experimented trying different cone sizes and lengths before deciding on the cones presently used. At the time I was interested in only modifying my failing CT3 muffler, doing a muffler for Dave, and maybe one or two more for a couple of riding friends. It was Dave's idea to bring this modification to the rest of the Yamaha forum members AND it was Dave that came up with the name "Sleeper Pipe".

So it is time to move on. Dave and I are very happy that so many forum members have benefited from this modification.

Congrats on a successful run to you and Dave.  I miss seeing you guys in Gorman.  I hope all is well.

Many thanks to both of you! 

I imagine it was a lot of hard work....  and more of a "labor of love" than any sort of profitable venture.  I'm honored to own a sleeper pipe and I greatly appreciate all that you and Dave have contributed to the community over the years!!

Sorry to hear the sleeper pipe era has come to an end, especially as my ‘70 CT1 is next in my queue and a sleeper pipe was part of the plan. Put me first in line if you ever have the itch again….

Any chance you could share the specifics of this modification so that others can benefit and do themselves? Wish I had known about these earlier.

Thank you both very much for all that work!! I can vouch for the effectiveness of the modification(s)!

If you were to post up what was done perhaps someone else might 'take up the flag' and make a go of it? 

As it is, I guess I have a collector's item!!!

I have considered making sleeper pipes for people in the past but didn't want to step on anyone's toes. you can see how I made mine in the thread "dt360 scrapper bike"
I'm busy this month but next month I was thinking to start making pipes for DT
