Yes, Rusty, I am. However, the $400 or so that it would cost me based on local estimates I've obtained, I decided to wait for a less expensive approach. In the meantime, given that the price on the HushPowers have come down, I decided to get two and simply hang them of my two headers for the present.

If I later go to one exhaust, I'll just have a spare {:>)

Looks like there will probably be a net weight reduction of approx 1 lb. But the sound reduction should be much higher {:>).

Hi Ed,

Sorry if I missed this (been kinda skimming the posts recently), but are you planning to make a more conventional system using just one one muffler? If so, I won't be surprised if you don't end up making more power, AND getting quieter exhaust. What will Ron have to complain about then :-)

By the way, I see you must have access to the resonator - did you ever try just the resonator by itself as a muffler?

I bought the resonator when someone else (sorry, can't recall who) mentioned it on the list. I thought it might be at least enough of a muffler to work for the single rotor, and it's clearly lighter. My plan is to try it and see how it sounds. I still have the muffler set up to use on the single rotor, so perhaps I could get a comparison between the two. This is just another good reason to run the single rotor on a test stand for a while, to sort these things out.
