>What does it sound like? 

It is definitely louder than the “Tangential” setup I had before. But it isn’t intolerable at all. I have no idea, of course, what it sounds like when going over 5000RPM. But at 4500 RPM and running between a row of hangars (lots of reflective surfaces) it was OK.

 

>Is it louder than using the cast iron exhaust manifold with a short pipe, I know what that is like (used it on first test start of my 13b)? 

Couldn’t tell you. I don’t think I’ve ever heard one up close that has the cast iron.

 

>What about the cost of this good looking set up. If not too expensive and not too loud I would be interested in one on my Cozy. 

The cost was $685 and that included a couple of SS clamp brackets (that I didn’t use L ). 

 

>Would it give more power than the stock cast iron exhaust?

Absolutely.  The cast iron exhaust is in the same boat with the tangential muffler – lots of back pressure. This exhaust design helps the engine “breathe” much better and, therefore, produce more power.
