Leading Edge Exhaust Systems, LLC was
founded by Dane Wagner in January 1995. The primary
reason was to develop new innovative exhaust systems
for a variety of General Aviation aircraft. Our sister
company, ABC Mechanical Services (FAA Approved Repair
Station FG4R179M) was the impetus for starting LEES.
ABC was founded in 1985 and within 2 years was certified
to do a myriad of welding and nondestructive testing.
After performing literally thousands
of repairs it was obvious what was needed to develop
entirely new systems. This led to LEES which is responsible
for new product development and manufacturing. Being
involved in auto racing, since a young age, inspired
Wagner to incorporate existing automotive technology
into LEES product line. He has welded at the Indy 500
in 1994 and has an open invitation to participate at
the Lincoln Electric Welding Shop, N15.(
see photo's in photo gallery). The inherent design
flaws were identified in OEM systems and new prototypes
were developed. Radical design changes were made and
were unique enough to receive numerous US Patents.
One of the main challenges was to incorporate
laminar flow technology in systems that would be direct
replacements and still fit within the confines of the
existing cowlings as well as meet FAA/EPA noise limitations.
We do not use the standard stamped out half sections
that are welded along a longitudinal seam. This style
can create transverse flow before the exhaust gases
exit the collector resulting in greater back pressure,
turbulence and overheating. All of our systems utilize
separate equal length mandrel bent primary tubes that
act as an individual exhaust pipe for each cylinder.
This helps balance the cylinders with regard to back
pressure, cylinder head temperatures and also helps
eliminate hot spots that are very common in existing
systems.
All of our products are FAA/PMA approved.
Our goal at Leading Edge Exhaust Systems, LLC is to
design and build exciting new exhaust systems that
perform well and most importantly are reliable. We
will not compromise quality. Our products are competitively
priced and use only premium grade materials.We are
setting the standards for General Aviation aircraft
systems now and into the future! Please check our website
regularly for new product updates.
