Mike,
If you go check out the DNA muffler, and please post a report for the group. Be sure that you're looking at the Gen II and not the Gen I. I'm told there is a big difference in the two. The Gen II's are much more durable, or so I'm told.
I'm considering the 1040 because of the slimmer 4" body.

Hope this turns out to be a good choice. A
functional off the shelf muffler that holds up would be great. The website says
there's a dealer just a couple miles away - might ride down today and see if
they stock it. What muffler did you order Mark, the race series? With what
inlet/outlet?
Anyone have any idea what B2 stainless
is?

Does anyone on the list have any real-life rotary experience
with the DNA Gen II muffler ( http://www.dnamufflers.com/DNA/main_DNA.html)? It is an interesting design in
that it has no packing material to burn out. Instead, it utilizes
ladder-rungs, which they call "internal sound diffusers", which resemble
a chain of DNA down through the center of the muffler body, which is made of
304 SS. Their web site claims that the racers use them with great
success. From speaking with a sales rep, they claim there the rotary
crowd uses them too. I'm considering purchasing one of their FULL
THROTTLE COLLECTOR mufflers (P/N 1040), but thought I would check to see
if anyone else has used this style muffler. This muffler has a 3"
inlet/outlet with a 4" body. So it is compact enough to fit
inside my cowl. My exhaust header has a 3" swivel joint, so it
should be a good fit.
