Joe,
What does it sound like?  Is it louder than using the cast = iron=20 exhaust manifold with a short pipe, I know what that is like (used it on = first=20 test start of my 13b)?  What about the cost of this good looking = set up. If=20 not too expensive and not too loud I would be interested in one on my=20 Cozy.  Would it give more power than the stock cast iron = exhaust?

Obviously the Tangential = muffler=20 sucks (actually blows) when it comes to performance! WAY too much back = pressure.
