Lycoming 0-290 Tuned Length 4-1 Performance Stainless Airboat Headers
Performance 4-1 Tuned Length Stainless Steel Airboat Headers- Lycoming O-290 135 HP
The newest line in performance Airboat Headers is here! With performance applications for over twenty different engines (including 4 & 6 cylinder aircraft engines) we have off-the-shelf solutions to all of your airboat header needs!
This Lycoming O-290 performance 4-1 header is hand-crafted from all American Made 304 stainless steel materials, and specially designed for the 135 HP O-290 engine.
**Many combinations available in 316 Stainless Steel for salt-water and brackish airboat applications- call for details and availability**
Current lead times: 3-5 weeks

We start the built with a CAD designed, laser-cut 2-Bolt flange in 1/4" 304 SS designed for the Lycoming O-290 cylinder ports.
From there, we use mandrel-bent tubing (bent in house) to create the runners out of 1 3/4" OD tubing. With engine simulations and performance taken into acocunt, these headers are built with tuned length runners to maximize exhaust wave pulse propagation for the most efficient and powerful airboat headers on the market.
Up next we precision craft the 4-1 merge collectors to accurately fit the runners, and complete the system with either a 2", 2 1/2", or 3" OD collector exit- depending on performance requirements.
The integrated merge spike increases exhaust scavenging for superior exhaust velocity, and greater engine volumetric efficiency.
From there, the entire system is argon purged, and hand-TIG welded by our in-house professionals.
Using our time-tested methods and performance racing knowledge, we are able to bring these headers together in an efficient, and affordable manner for any airboat application. Order online or give us a call today!
Looking for a bit of thermal protection? We do in-house ceramic coating for airboat applications as well! With years of expertise, the ceramic coating we offer will provide additional elemental protection, as well as reduce radiant exhaust heat. Plus, it looks damn good.
Have a particularly difficult application or don't see what you need? Give one of our airboat specialists a call for a mockup kit to design your very own custom set today!
