Hey LMLers,

 

We bought these IO-550 exhaust pipes from Lancair that were designed and built for the Legacy by Chuck Brenner and John Forsling (Forsling Aviation).  The late Chuck Brenner was working to achieve a “tuned exhaust” -- though in talking with John Forsling he says at the relative low rpms of an IO-550 that no benefit is noticeable.  He had some dyno testing at Barrett that confirmed that.  I’ve noticed a few Legacy’s at Oshkosh that seem to have the same exhaust system. 

 

 

 

I’d appreciate hearing from pilots flying with them on how they perform.  For example, the exhaust is a little longer -- does that help with heating around the exhaust where some stock designs have blistered nearby paint?  Does it help with oily grime on the belly?  Does running a heat muff off a single cylinder exhaust pipe perform as well as off the end where three are collected?  Someone familiar with Forsling’s exhaust pipes said they have a very nice “exhaust note”  – notice a different sound?  Anything else?

 

Thanks,

 

Valin Thorn
