Leading Edge Exhaust Systems

Cessna Exhaust Systems, Piper Exhaust Systems and more

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. 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 aircraft parts 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 parts now and into the future!
