Matt,

This reminds me of the Tornado device that you put inside your air filter to spin the air around. They make all kinds of claims about improved power and gas mileage, etc. Test results show no appreciable difference in performance. I would guess that these mufflers will fall into the same category. It is possible that they will make a more pleasing (deeper) tone, but, I really doubt that, too.

In order to make the tone deeper you need to have a larger resonance chamber or longer tubing. The cylindrical shape of this muffler suggests that it does neither. The price is a little high but good quality stainless mufflers are over $100.00 and these appear to be polished. I paid $150.00 each for Stainless Steel Specialties double flow mufflers and I'm happy with their deeper tone and lower sound level.

Personally, I'll wait for a consumer test before spending this much money on mufflers.
