It is definitely louder than the = “Tangential” setup I=20 had before. But it isn’t intolerable at all. I have no idea, of = course, what=20 it sounds like when going over 5000RPM. But at 4500 RPM and running = between a=20 row of hangars (lots of reflective surfaces) it was OK.=20

>Is it louder than using the cast iron = exhaust=20 manifold with a short pipe, I know what that is like (used it on first = test=20 start of my 13b)?

Couldn’t tell you. I don’t think = I’ve ever heard one=20 up close that has the cast iron.

>What about the cost of this good looking = set up.=20 If not too expensive and not too loud I would be interested in one on = my=20 Cozy.

The cost was $685 and that included a couple = of SS=20 clamp brackets (that I didn’t use L ). =

Absolutely. The cast iron exhaust is = in the same=20 boat with the tangential muffler – lots of back pressure. This = exhaust design=20 helps the engine “breathe” much better and, therefore, = produce more=20 power.
