New: Dual Exhaust System SS Hotpipes

CAP is excited to announce that we have teamed up with St. John Manufacturing, LLC to introduce a new product ready to offer you for the Continental powered Taylorcraft and Luscombe 8 series. These parts have FAA approved design and are fabricated in accordance with 14 CFR 21.9(a)(5)(6) with airworthiness approval by certificated maintenance personnel.

 

 

It is a complete exhaust and heater muff system that is FAA approved for Taylorcraft L-2 and BC Series airplanes (STC) and can replace the original Luscombe 8-series Exhaust and Heater Muff System p/n 09607. We have named our system SS HOTPIPES! This system includes refinements over the original design, which result in...

•  perfectly fitting heat muffs with no air gaps for optimal efficiency
•  drastically improved heat rise in both carburetor air box and the cabin
•  simpler to manufacture and easy install
•  more durable shroud/muff design (by far) for minimal maintenance
• the highest grade construction with all 321 stainless steel materials 
• the right and most reasonable price

 

** TAYLORCRAFT IMPORTANT NOTE: **

Talk to us about the need to re-locate your Gascolator for this exhaust upgrade!

 

EXPERT FABRICATION: You will note that these superb parts have many modernized fabrication features of the highest quality.  Made possible only by the polished expertise of Keith St. John of St. John Manufacturing, LLC who has been repairing and building aircraft exhaust system components for more than 20 years in the general aviation marketplace.  

 

Our aim was to keep the same great split header design, but to solve the problematic heat shrouds/muffs that have aggravated Luscombe owners for decades. Those days are over. We also incorporated design details that come from modern exhaust systems to make the best and most practical Luscombe exhaust system available. 

 

 

 

And the main feature setting SS HOTPIPES apart from the rest are our special radiant heat air flow ribbons. We know that original systems barely met the carburetor heat rise requirement and most aged systems won't even meet it. SS HOTPIPES have demonstrated a substantial increase over the original design with plenty of warm air to spare. This is NOT the Hanlon-Wilson muffler design, which we love, but we have found them much more costly to make and only slightly better heat than SS HOTPIPES.  So, our decision to go this route was based on keeping things simple and offering the best performance value. We do have a prototype SS HOTPIPES version based on the Hanlon-Wilson design currently in testing, but that system will be much higher priced. 

 

Much has been invested in processes, equipment for welding, tube forming, and tooling. In fact, we are ready to supply new 321 stainless steel exhaust systems and 4130 engine mounts to your drawing spec for any piston-engine aircraft, starting NOW. We can also provide one-off custom weldment assemblies and numerous types of repairs, (So, send us your RFQ's.)

 

 

As for SS HOTPIPES, they are now FAA approved as optional on our Taylorcraft Engine Upgrade STC's # SA1-210 and SA02164LA. PMA application has been made by Airmotive Components, LLC under license agreement from CAP. As such, Certified Aeronautical Products, LLC (CAP) is the design approval holder. We expect PMA in the 1st quarter of 2022. But we are ready to supply parts for your Owner Produced Parts needs right away.
