2 things that you've probably got identified.


Insure the lengths from the exhaust ports to the 2-1 collector is correct for your exhaust scavenging tunage... (note the industry term "tunage").
Insure the volume/flow of the muffler is large enough to prevent it from introducing too much added back pressure, changing the scavenging.

2-1-2 systems were designed that way to split the duties of handling such large exhaust pulses from a v-twin engine.

From my past experience with my RC51...

[QUOTE=K2ride]Looking at the possibility of fabricating a two in one set up like the Dakar bikes:

Any ideas on what`s involved here?
- Materials to be used
- Carb & engine tuning
- Heat dissipation

Try:
Burns Stainless
1013 W. 18th St. P: 949-631-5120
Costa Mesa Ca, 92627 F: 949-631-3184

These guys do real high end stuff for NASCAR.
I asked them to make a two into one 1 1/2 in dia stainless steel section. Inside and ouside welds are smooth as a babies bottom!
