That's how mufflers have to be tested - there is no heat exchanger in a muffler, besides ambient air exchange (wholly inefficient, so negligible at best.)
The problem comes in when you start extracting heat from the exhaust. The exhaust will lose velocity because of the heat exchange.
I'm not saying it won't work, and by all means, please, try it. I'd do it, but I don't have $160 + shipping to spend on it right now.
Please, keep us updated with your results!
