I had a nightmare that I bought one of these and it fell off over a corn field somewhere.
Geesh guy, never never strap an ESComp pipe to the outside of a plane. Always run it inside a belly.
On the other hand, they are so lightweight, they just float down like a feather. If you can run faster than me (I can't run with these rickety knees recently replaced) you might catch it on the fly...LOL
Seriously, I always soft mount the pipe on a Dave Brown type or similar hush pipe mount. And I always wrap the area of contact with nylon or teflon tape to keep abrasion at bay. Or a piece of bicycle inner tube. On the connection to the header, you can use turbo hose which will last maybe 100 flights. But you can just zip tie this to the header stems.
Teflon tubing also works well except it tends to leak and requires klunky hose spring clamps to hold it. Ed Skorepa gave me a simple tip I want to pass on....screw in a couple 4-40 button heads into the header stem and pipe stem to serve as bumpers.
My solution is probably the best tho, if I may say so. I make my own connectors from ceramic fabric and high temp, gas resistant Permatex Ultra Copper. These are much thinner and they handle 1500 F no sweat, so 600F is tweedle thumbs time. This solution allows you to form any configuration to fit a specific application. If you don't want to tackle the job, I offer a service for that. PM me if interested
