Thank you Ron. I’m planning the M1B with stock sump, so I guess that answers my question.

FWIW, I have the Trombone on a M1S with a Superior Cold Sump.
Fits perfectly. Follow the instructions, easy to install and no issues.

Let's be honest, that stuff is great for loosening joints, but at exhaust temps - it burns off in a few hours of operation.

For this application, nickel based anti-seize works well and will last longer, or use Loctite 299175 which also has a corrosion inhibitor good for 2400ºF.

I have the same engine and exhaust and I would like to see how you installed the hanger brackets for the exhaust.

Thanks
Ken

Default Ball joints

Keep the muff joints loose ish. I over tightened and over 100 hours or so the weldment into the muff broke and left it hanging. Keep it moveable and lubricated

Ken, here's what I have on hand.
I will be at the airport later today and can take more photos for you if needed.

Absolutely, it's part of the installation instruction to keep lightly clamped.
And as Ron suggested above, use nickel anti-seize in the joints.

Default Flares for hangar tubing

It's been mentioned before, but a rehash is always good:

The tubing that form the hanging support for the ends of the tubes is prone to slipping.

In my mind a rolled bead at each end of that tubing would be the perfect solution so that the hose clamp could be mounted just above the roll and lock everything in place.

I didn't have that tool and used a very slight flare instead, works great. Others have had success with knurling or just roughing up the surface with a stone to give it some tooth.

Default Alternative hangers

I've never liked that design, they always seem to slip or break and it looks like something cobbled together at the last minute with scraps that were laying on the shop floor. No way to treat a beautiful $2K exhaust system IMHO.

Not an RV, but here's what I'm using on my biplane build. $35 each from one of the auto hotrod shops.

Yea, a local A&P who had a look at my project also recommended anti-seize on the slip joints. I assume you need to pull the exhaust completely to apply it, as you need to move the pipes to work the material into the joint.
