SLEEPER PIPES FOR YAMAHA ENDUROS #201
I was thinking (hoping?) the master sleeper pipe team of Meis and DVM might be able to install a cone to internally shorten the tuned length to better match the porting and make the pipe work at higher RPM to match the cylinder...

I think with the way the pipe starts on the left side of the bike and stinger/ muffler on the right makes it difficult to get a cone in there. It doesn't angle toward the muffler side per sey but just jogs the rear cone to that side. It also has a few dents to go around 2 frame tubes, and carb cable. Also further up the belly has a dent for spark plug boot clearance. Seems this jogging and clearance in between these dents would make it hard to stuff a cone in there, dunno. I believe I saw pictures here (on the forum)that showed some baffling material in the belly behind perforated steel, and a plate as a crude reflector in the convergent cone area. It has a hole to let gas pass through. My memory may have failed but you might be able to pull that up with the search feature.
