    I’m 7 years behind the last guy asking questions about 912uls springs. Not sure what exhaust I have, but the standard 66mm springs seem way too short. Right now, there is a hodgepodge of motorcycle or snowmobile springs on the one. Photo attached. I think I need something around 88mm. Photo attached.

    That's not a stock exhaust system that's why the 66 mm springs won't work. Not sure what spring your longer one is.

    What make aircraft is this? Maybe someone else will have one and the answer for you.

    Remos G3. Past owner says it’s a stock Remos exhaust. Maybe it’s something special for the fit into the cowl. Maybe need to get my hands on a Remos maintenance manual.

    Try this website.

    I googled the Remos G3 and other springs popped up. Some were around 90 mm. Those may work.

    Try web searching and you may find them.

    Since we are covering all things springs, it should be mentioned that it is important to use the proper tool when installing or removing them.  If you grab the spring hook with a pair of pliers you can scar the surface of the spring and create a failure point.  Using a proper spring puller avoids this, and may extend the life of the spring.  I personally like SS springs, and I’m still safety wiring through the middle of the spring, with a stripe of “ultra copper RTV silicone” down one side.
