Call DA, they should be able to help you. I hear 2-1 can systems have problems with surging. But, like I said, DA should be able to answer your questions.

I have seen a 2-1 cannister system with a DA-100. Seemed to work pretty well, although the engine wasn't quite as steady at low RPM than an engine with stock mufflers. It was quiet though - all I could hear was the prop noise.

I used the 2 into 1 with a DA-100 installed in a Fiber Classics 2.6M Extra. For whatever the reason it was not RIGHT! Idle surged and transition was not all that, I was told by Dave Johnson and several other engine reps this had been a commonplace occurence. It might have something to do with the header length, just guessing. BUT your limited in this model as with most. I gave up and pulled the cannister. I even swapped out engines with a known good running unit to no avail.

I'll bet you won't find a truly satisfied user with this combination.
