Think Green!! Save on High Fuel Costs!!
Leading Edge Exhaust Systems’ hand built, custom, equal length exhaust collectors reduce back pressure (balanced to .05” psi between all cylinders) and balance the engine operating characteristics so well that a single horsepower is produced with less fuel when comparing LEES’ BSFC, brake specific fuel consumption, to the stock exhaust system, BSFC. Brake Specific Fuel Consumption is the amount of fuel required to produce one horsepower. In all of the dyno pulls using LEES’ pipes the BSFC was much lower when compared to the stock OEM exhaust system.. If the pilot cruises at the same engine rpm level as before the installation of LEES’ “Bad Boy” pipes fuel consumption should be lower. Using LEES’ pipes the engine will be able to produce more RPM’s so it is up to the pilot in command to have enough discipline to keep his foot, or hand in this case, out of the throttle in normal cruise.
Other applications will prove there is more power available. If you stop and think about the definition of a horsepower being the amount of power required to raise 33,000 pounds one foot in one minute, the only way you would notice it is under a load: short field and glassy water take offs; obstacle clearance or heavy gross loads.
My son gave a good analogy when he said it would be like me pulling up next to his pick up, in my Pro Street 600 Hp small bock77 Vega, on the highway and we both are cruising at 55 mph. You would not see or notice any difference between the vehicles until I romped on it. Obviously when I put it under a load the horsepower advantage would be very evident. So having more power has very positive aspects but it requires self discipline in order to realize fuel savings.
Please refer to Doug Drum’s own recorded measurements, before and after installation of LEES PA-12 180Hp pipes, on his good looking PA-12. Doug’s plane is shown on floats on the PA-12 180 Hp Short Mount product page. Please note the GPH reduction. The 180Hp exhaust pulled 22 more Hp than the stock system during a dyno test performed at LYCON Engine Rebuilding in

Leading Edge Exhaust Systems is in the process of discussing production of the US Patented Cross- Flow dual exhaust system to fit the Cessna 180, 182 and 185 model aircraft with some prospective investors. They have asked us to corroborate the market potential so I’m turning to you, the aircraft owner, to assist us. The pre STC advance purchase discount will be discounted 10% for the first 100 units. The advance purchase price will be $4495.50. We offered a similar type promotion for the Piper Super Cub exhaust in 1999 and 2000 with great success.
Once we receive your data it will be entered it in a computer data base and will be assigned a priority number. It could take several months to acquire data but more than likely will probably be much sooner because the market is so large. Please supply us with the following: Your name, address, phone number, email address, aircraft make and model, engine make and model, floats, wheels and or skis, propeller and engine mount.
We feel confident that the prospective investors will contact some people on the list as part of their due diligence process.
When we get closer to going into full time production we will contact you in the priority order we assigned when we solicited your data. We will require 40% down or $1798.20 that you will be required to supply within one week. We accept Visa and Master Card credit cards. The balance due will be collected once your system is completed. If you cannot pay the 40% down then your name will be moved to the end of the list.
If you are not one of the first 100 customers we will still apply a priority number to your data and you will be contacted as the systems are completed. You will be contacted by the priority number assigned.
Please contact your friends or other pilots that would seriously be interested. It has taken too long, as it is, and if we can get the endorsement of this prospective investor group then we can finally get this show on the road.
I cannot give you an accurate production time frame at the present time because the bend and press form tooling will need to be manufactured. The faster we receive the customer supplied data the sooner we can go into production. As history has taught us prices will probably keep increasing so the advance purchase price will save you a substantial amount of money.

The PA-18-150/160 Hp model exhausts were recently approved to include the new RMW and CAHF as options to the original STC’s.
The Revised Muffler Weldment, RMW, and the new Carburetor Heat Flange, CAHF, are now approved for all models shown on the approved model list, AML. The 180 Hp model is currently undergoing carburetor heat testing and should be approved soon. The RMW muffler has exactly the same high performance internal baffles as the standard issue muffler. Most external flanges welded to the can are needed for carb heat generation have now been removed, substantially decreasing the parallel to the grain fillet welds and increasing life expectancy. It’s not uncommon for our muffler baffles to last over 2000 hours. The RMW muffler can now be used entirely for cabin heat which is a real plus in cold weather. The left side is utilized for main cabin heat and the right side is for rear seat heat. The carburetor heat is now generated in the CAHF. The RMW muffler has a 1000 hour/10 year warranty. If you place and order for a new exhaust system.
The PA-18 150/160 Hp exhaust systems with the Carburetor Heat Flange, CAHF is priced at $3495.00. RMW and CAHF can be ordered separately to upgrade the original exhaust system. Call for current prices.

Pre 55 Cessna 180 dual exhaust system. We have expanded the list of aircraft to include more models even though pre-55 has grandfather rights regarding noise testing. No noise testing is required provided the logbooks can document it was flown prior to January 1, 1955. We decided to include several more years simply because there are more model years that the system will fit. We are presently involved in developing the product specific completion program, PSCP. When it is completed and the specific aircraft we need is located, testing will commence. In the meantime, numerous field approval have been granted nation wide. Please look at our Pre STC advanced purchase special. You save $500.00.

GlasAir Sportsman 2+2 prototype was completed utilizing LEES power proven Super Cub muffler. Four new risers were developed using our Equal Length theory. The pipes were sent to LY-CON Engine Rebuilding in Visalia, CA. WWW.LYCON.com, phone number 559-651-1070 where dyno tests were completed. The high performance 180 Hp engine not only produced 15 more Hp but RPM's were increased 200 rpm's. The test was done utilizing the stock no baffled equal length exhaust system and the LEES new 180Hp equal length pipes. No other changes were made except the exhaust system was swapped. All other variables remained exactly the same. We are working with the aircraft owner and mechanic here in Anchorage to install and perform flight tests soon.

Maule manufacturing and LEES are in the process of collaborating to build a new equal length component dual exhaust similar to our time proven 2000 hour/20 year Cessna 205/210 dual exhaust system. Just as soon as we get an IO540 powered aircraft lined up we will proceed with developing a new system. We will have the system dyno tested once it's completed. We are anticipating designing and building it over the winter months of 2006. We have over 20 years repairing the Maule exhaust in our Repair Station ABC Mechanical Services, FG4R179M, and knows what needs to happen to have a much better performer and very high TBO exhaust system.

LEES 150Hp equal length Super Cub High performance exhaust system was installed on Murphy Rebel in Canada. The owner is in the process of getting us some photos to publish. He said rpm's increased both static and in flight. In flight cruise speeds also increased. The exhaust system the owner installed after the plane was completed was the old tandem style Piper PA-12 exhaust system. We knew that the rpm and power would increase based on previous dyno tests at LYCON Engine Rebuilding using LEES High Performance exhaust. If you are building a Rebel and utilize a Piper PA-12 short mount engine mount our pipes will probably fit. I believe you can request an engine mount like our customer built and gain great performance. It’s worth a try!!Our Canadian customer our system fit like a glove and produced great power. We will publish the data and picture as quick as we receive them from Canada.

Dyno
tests just completed comparing Straight pipes,
Stock Super Cub, and Sutton exhaust system.
Read the eye opening results...
The first thing everyone
should be aware of is that LEES requested the following
dynamometer testing be accomplished at LY-CON Engine
Rebuilding. LY-CON had no involvement other than
performing the tests at LEES' request. If you have
any questions regarding the testing please direct
them to Dane Wagner Sr., President, Leading Edge
Exhaust Systems, LLC. LY-CON Engine Rebuilding
is entirely too busy to handle extraneous phone
calls.
We want to start out by giving you a little background
on the very first dyno tests, done in about July
of 2004, that compared Leading Edge Exhaust Systems,
LLC's PA-18ESA exhaust system and LY-CON straight
pipes. LEES wanted to confirm our design by testing
our PA-18ESA with inherent back pressure to straight
pipes. The tests were done at LY-CON Engine Rebuilding.
LY-CON is the largest engine rebuilding shop on
the United States west coast. LY-CON is a Lycoming
and Continental approved engine repair facility.
LY-CON is located in Visalia, California.
The test results demonstrate
how well Leading Edge Exhaust Systems, LLC's U.S.
Patented Super Cub exhaust perform when compared
to LY-CON straight pipes. The typical assumption
is the straight pipes out perform exhaust systems
in general. This standard assumption is based on
the belief that straight pipes produce less back
pressure than an entire exhaust system, which is
usually true. (Straight pipes are what most engine
shops and engine manufacturers use when they test
an engine.) One thing usually omitted from this
line of thinking is that LEES developed a muffler
baffle that was unique enough to be awarded a United
States Patent. LEES used balance, lower back pressure,
valve overlap and designed a firing order into
the exhaust system to enhance engine performance.
The extremely well-balanced back pressure between
all four cylinders, using LEES' PA-18ESA, is within
.05psi. and is a much better balance than the stock
OEM exhaust system. The tests results also show
the degradation in performance when the muffler
baffles were removed from the LEES' PA-18ESA muffler.
Some companies claim that power is lost when the
muffler baffles are left in the muffler. These
specific dyno test results are also included in
the "What's News?" section.
We encourage you to read them.
The first comparison
tests were done a couple months ago using a Lycoming
O360A1A engine factory rated at 180Hp. The Dyno
was set up to use a constant speed prop, which
is normally used. The LY-CON straight pipes pulled
190Hp @ 2740 RPM and the torque was 366lb/ft. The
Leading Edge Exhaust pulled 202 Hp @ 2780 RPM and
the torque was 370lb/ft. Lees pulled 12 more Hp
and more torque with the entire exhaust system
installed. Another important thing to remember
was LEES' muffler utilizes our patented muffler
baffles. Unlike other manufacturers who remove
baffles from an exhaust system for dyno testing,
there are no "Gutless Wonder" claims being made
here.
The most recent tests,
performed in January 2005, utilized a Lycoming
AEIO-360B1F- LY-CON aerobatic, high performance
ported 180 Hp engine that produces 200Hp. The
two important things to remember are that a fixed
pitch prop was used and the throttle setting was
identical for all three tests. The "only
change" was the exhaust system used
for that specific dyno test. This gives
a true and accurate reflection regarding Hp, Torque
and RPM when only one variable is changed, that
being the exhaust system.
The three tests were
done back to back and used LY-CON straight pipes,
the factory issued Super Cub OEM exhaust system
with muffler baffles and the new Sutton Exhaust
System. The Sutton Exhaust as advertised on their
website has no muffler baffles, and uses the shortest
path for exhaust egress. Sutton claims this provides
better performance and 5% more thrust.
Now you can make an educated
decision based on the Dyno test data supplied.
1st test: LY-CON
straight pipes 204HP-396 lb/ft torque @2740 RPM
2nd test Factory
issued OEM Super Cub Exhaust System that includes
muffler baffles: 185 Hp-370lb/ft torque @ 2650
RPM
3rd test Sutton
Exhaust 176Hp-356 lb/ft torque @2630 RPM without
muffler baffles
Now it's
your turn do some basic math. If you have a stock
engine and a stock Super Cub OEM exhaust and know what
the factory numbers are; HP; Torque; and RPM you
can do your own comparisons. Each individual engine
can have different test results. The test results
we discuss here were for the model engine listed.
The engine test results can vary based on these variables,
including temperature, humidity, altitude, mixture
and propeller.
We hope this test data
will help everyone understand the actual and
more importantly realistic performance
gains before they spend their money on products with unsupported
claims.

Dyno Test
Results reflects the difference in Hp and torque using
the same engine when comparing the OEM (stock) or "other" Super Cub exhaust systems to the Leading Edge
Exhaust Systems' part number listed.
Note: Dyno
test information is obtained doing static pulls on
an aircraft engine dynamometer. The following test
was conducted at LY-CON Engine
Rebuilding. The
results are presented for "professional pilots" and
mechanics that assume when baffles are removed from
the muffler, the engine will produce more horsepower
and torque. The test results will probably surprise
you. With no baffles in muffler and the engine leaned
to peak rpm the engine lost
2 Hp and 7lb/ft of torque and in the full rich
mode the loss was an additional 3 Hp and 3lb/ ft
of torque. The total
loss was 5Hp and 10lb/ft of torque, full rich,
when compared to the same Leading Edge Super Cub Exhaust
System PA-18-150ESA with muffler baffles installed
and leaned to best rpm.
Attention High Performance Experimental Crowd! Check this
out. Using LY-CON's "Bad
Boy" 11:1 compression 160 Hp. Exp. engine and Leading
Edge Exhaust Systems' P/N PA-18-160ESA together pulled
197 HP and an unbelievable 371.2 lb/ft of torque. That
is more torque than the 180Hp engine produced with nearly the
same Hp.
LEES just received US Patent # 6,796,402 for the unique muffler
design the new
Cessna 180,182 & 185 "Cross Flow" dual exhaust
system.
LEES new
Cessna-180 "Cross Flow" exhaust was recently dyno proven
at LY-CON Engine
Rebuilding. Gain
13Hp and 28lb/ft of torque over the stock exhaust
system on an O470 engine leaned to 2600 rpm using the
new Leading Edge Exhaust Systems', LLC "Cross Flow" dual
exhaust system.
The latest Dyno test was done at LY-CON Engine Rebuilding using one of Ken's IO550 Exp. 11:1 compression
ratio engines. It pulled 354 Hp and 668 lb/ft of torque
with the stock Cessna exhaust system @ 2700rpm's. Using
Leading Edge Exhaust Systems' new "Cross Flow" dual
exhaust system it pulled 381 Hp and 708 lb/ ft of torque
@ 2700rpm's, a 27 Hp gain and 40 lb/ft of torque!

Leading
Edge Exhaust Systems,LLC is now accepting advance
orders for the Pre-55 Cessna 180 aircraft dual
exhaust systems. Exhaust Systems will include new
US Patented 3-1 exhaust collectors, two new mufflers,
shrouds, tailpipes and hardware. Each advance
order sale price, $3495 that is $500 less than
the anticipated sales price of $3995.00. Each advance
order will receive a priority number. The priority
number will be printed on the invoice/receipt.
The exhaust systems will be built and delivered
in the same priority number sequence. Customers
are urged to place orders as soon as possible due
to the anticipated high demand. Anticipated STC
approval time is one year. Leading Edge Exhaust
Systems, LLC reserves the right to terminate this
offer at their own discretion. After
approval for the early model Cessna180's LEES
will concentrate their efforts on the newly patented "Cross
Flow" dual exhaust system for the later model Cessna
180, 182 and 185's.
LEES is starting the FAA approval process for the Cessna 180, 182 & 185
muffler baffle kits. Kits will be approved
for sale and installation by other facilities.
LEES separate repair station will also install
them for a flat rate. LEES
is going to offer, what we feel is, the best warranty
in the country. Our Cessna US Patented,
FAA/PMA approved 205/210 exhaust collectors offers
a 2000 hour or 20 year warranty. Muffler
baffle warranty will be 1000 hours or 5 years.
Other common muffler baffles usually offer 1 year/unlimited
hours. One of LEES' customers has a set of the new US Patented 185 muffler
baffles installed that
presently has 2000 hours on them. LEES
experience with muffler baffles has shown that
the OEM muffler baffles usually last about 300
to 400 hours. To repair the muffler the entire
exhaust system has to be removed, muffler gutted,
rebuilt and then reinstalled. Downtime and expense
is incurred. LEES say their US Patented, FAA/PMA
muffler baffle repair kits will be competitively
priced and will
far outlast other baffles.
LEES plans to have FAA/PMA approved parts available for exhaust system
repairs covering all of the most popular
and common exhaust parts & fittings. LEES
will be the only United States manufacturing
company,
that their aware of, selling FAA/PMA approved
exhaust system repair parts. LEES will update
their website
periodically so make sure you check it out! www.wemakeyoufly.com.
