Press Release: Newest Chabord
High-Performance Exhaust System Certified on Cessna 172 models
Epagny,
France: CHABORD Exhaust
Systems has just earned EASA certification for its new stainless steel /
Inconel* “eco” exhaust system for the Cessna 172R and -S models; the company has
filed for reciprocal certification with the FAA, and “We expect no surprises,”
according to company President, Alain Chabord.
The STC includes
everything the customer needs. Using the customer’s exhaust gaskets, all-new
materials and hardware carry exhaust through the collector to the heat muff and
special muffler [with replaceable packing], and to the exhaust tip. All
necessary brackets and detailed instructions are also
included.
The Chabord Eco
Exhaust system combines meticulous craftsmanship with a design that enhances
engine performance while lowering noise emissions. The entire system, from the
flanges at the head to the tip of the exhaust, is designed to work as a unit and
built at the Chabord factory in France, where high performance exhaust systems
have been produced for over thirty years, exhaust systems that appeared in
Formula One and in many prototypes in rally and at LeMans, as well as on rare
collector cars like the Ferrari 250GTO.
In aviation,
Chabord performance exhausts have flown in Red Bull competitions; these
hand-made Inconel systems weigh as little as nine pounds, complete, for a
540-inch Lycoming, and are becoming ever-more popular in unlimited aerobatics.
Chabord also produces certified exhaust systems for many exotic civilian
aircraft, as well as for legacy aircraft whose factory support has run out.
Increasingly, stock exhaust systems are being replaced by Chabord’s better-made,
quieter, and efficient Eco Exhaust systems.
Measured
performance improvements include a 4-11db reduction in noise (depending on the
frequency measured, and at what distance; a decrease of the sound level by 3 dB
corresponds to a halving of sound intensity). Measured climb rate increases went
from 4.3m/sec (846 fpm) to 4.93m/sec (970 fpm), a 14% improvement after
normalizing for flight conditions.
Factory estimates
of 8% fuel consumption improvement and 50% engine vibration reduction are
reasonable. (More testing is required to get definitive numbers, but substantial
improvement is obvious in preliminary test.)
“We wanted to
demonstrate exceptional performance, quieter operation, and customer
satisfaction, before we announced this exhaust system,” says Alain Chabord, head
of the engineering and production firm that produces the exhausts. “We will be
showing this system, as well as systems for other popular aircraft applications,
including Van’s RV, Cessna C-150, -152 and -172; and the Rotax 912 series, at
Airventure Oshkosh this July.”
*Two versions are
available: V1 is all stainless, with critical parts (e.g., fittings and double
swivel tube) in Inconel; V2 includes these, and adds Inconel primary tubes and
4-1 tailpipe. V1 is priced at $3900USD, complete, including shipping to
the US and taxes. Both systems are available
factory-direct.
