I presume that you mean stainless steel exhaust system rather than "tunnels" - I don't know where to get stainless.  Got my exhaust (not stainless) from Custom Aircraft ( http://www.customaircraft.com/ ) and was pleased with price, quality and service.
 
However, speaking of "exhaust tunnels", some of us have installed/are installing exhaust tunnels on the Legacy. These mount on the bottom of the fuselage behind the cowling and are a continuation of the bulge on the underside of the cowling.  These are similar to what is on the IV and ES.
 
The theory behind them is that they smooth airflow out of the engine, decreasing cooling drag and decreasing CHTs, particularly when combined with a VG.  As with many other "speed mods" the before and after data is a little sketchy.  I didn't have the opportunity to fly before installation, so I can't actually say they do anything - except look cool.  But they do look cool!!

Does anyone know where I can get a set of stainless steel legacy exhausts tunnels?  They are not available from Ron Gregory.

Thanks

Russell
