Does anyone know what Josh Upperman is running for his head pipe? There is a large chamber attached to it like some of the KTMs and other enduro manufacturers.

Its a resonator. It lowers the decibal level without losing horsepower.

Understood, I guess my question is it available to the public or is it something Baldwin built for his engine experimenting with the dbs? Thanks

He doesn't build them on his production exhausts. He said its a pain to build them. Dasa has them on the Joe Byrd model. FMF has the Powerbomb and Megabomb which as essentially the same thing. Moto-Xperts does a resonantor as well.
