Todd,

From the looks of it, I would be surprised if it is even 5 pounds.  You can get more info from what appears to the parent company’s web site at http://stores.channeladvisor.com/vertexnow/.  They also have flexible exhaust couplings, and many other items that could be useful to our efforts. 

 

I have contacted them just this morning about whether or not they recommend using it on a rotary.  Depending on their response, I may follow up with another inquiry concerning their lifetime warranty.  I’ll post their reply when received.

Hi Mark;

    While I'm currently satisfied with the performance of my homemade "SpinTech" muffler, I'm very intrigued by this one. I could find no weights listed, but it looks like it shouldn't be more than ~7#. What I find most appealing about this muffler is the claimed "cooler" performance. It seems that they're implying an overall reduction in temps, due to less backpressure as well as a cooling effect within the muffler. As some of you may recall, I incorporated a muffler housing into the bottom of my fuselage to keep the muffler out of the airstream and out of the cowl, however while it doesn't get too hot, a reduction of this temp would be welcome.

    You should contact them for further details as I and I'm certain many others would be very interested.

It looks to be very streamlined, made of SS, lightweight, and has no packing. It sells for less than $200 (except for the 5” model).  This looks like this just might be what I’ve been looking for.  More info available at http://www.pickupspecialties.com/Aero_Turbine/aeroturbine_mufflers.htm.  Comments???
