Moki 2-in-1 Exhaust for S215 and S250


Moki 2-in-1 Exhaust fuer S215 and S250, will be oversized, you cut to correct length and solder the three pieces together. No soldering to the Moki required, it will simply clamp on

These setups give your Moki much more presence, a meaner tone. At all fly-ins even the Moki guys came up and asked me what motor I am running. The difference is subtle to the novice, brings a smile to the experts face. You may or may not even increase a small performance boost.

Two different versions available, one for the 5 cylinder and one for the 7 cylinder Moki 250s.

Not compatible with any other Moki



Place the two L bends on the two exhaust ports. Now set your line of sight up right in front of the motor, level with the exhaust. Now place the "Center-T" behind the two bends. Mark where the tubes need to end. The Center-T is over length as it has to fit all versions of the S215 and S250 out there, and they vary.

Now cut off with a centimeter too much length on each end of the bend.

Now slowly grind/cut away until everything slides together neatly.

 Most likely they will come together with a "kick", not in a straight line, which is fine.


Now add High Temp Gasket making Silicone (Permatex etc) to the two exhaust stubs on the ring muffler.

Prep the 2-in-1 metal surfaces

Slide the two L bends over the Center-T

Slide the whole assembly into place on the ring exhaust

Point the exit port of your Center-T to the preferred position

Silver Solder the bends to the Center-T


The fact that the exhaust ports on the ring muffler point AWAY from each other will lock the assembly in place, you are finished, install complete.
