Vetterman exhaust hangers

[gassman]

I have the "regular?" exhaust, not the crossover. Rv7 with io360 and superior sump. Could anyone share how they did it? Which way the clamps go on the exhaust and orientation. Do the ears of the clamps get bent to line up with the supports going to the oil sump bolts. And which engine mount tube is used to support from. Any help would be great. Pics would be even better. Thanks

Contact Veterman for help. he has severa lwas of clamping the exhaust.

Here are some images from when I was installing these (so ignore anything that looks unfinished). My exhaust pipes hang from the engine via a couple of the sump mounting bolts, not from the engine mount, so when things move around they all move as a unit.

That is correct. Tubes are attached at the sump bolts. Another pair ties the two pipes together.

Tip, put a tiny flare in the ends of the tubes and rough them up with sandpaper. It helps the rubber hose stay in place.

Found a few photos.

Thanks guys. I like the way that looks. My clamps are a little different. The sketch that came with it shows there were clamps going to the sump and the motor mount. I emailed Clint and have not heard back. Ill get after it after oshkosh

On my plans for the -6, there were a couple of bends called out in the flattened sections of the exhaust hangar tubes. Despite my best efforts at smooth bends with a decent radius, that's where I always got cracks and broken pieces. I subsequently learned to make any bends in small pieces 4130 sheet and connect those to the flattened (but straight) ends of the steel tubes.

My hangars would always come loose. New set up on the rv8 but would work on 6/7.

I dismantled a vetterman hanger that used fuel line as the connection. Stretched and deformed. I used high pressure air conditioning hose in its place. Like Larry said give it a tooth to grip to. Then I used screw type hose clamps and not worm gear clamps.

That's how mine is set up from 2016 but I've had a couple clamps break on the right side. Next CI, I plan to tie the pipes together as in the above images.

To those of you that are hanging your exhaust from the engine and not the engine mount: Why use the rubber tubes? Can’t you use solid stainless steel tube from the exhaust to the engine? There should be no-to-little relative movement between the exhaust and engine. I noticed on my work plane today (Super Cub) that is how they do it.

Ball joints?

Thanks. This looks like mine. My question: Can solid SS tubes (no rubber “bushing”) be used to suspend exhaust directly from the engine?

My guess is that the rubber tubing that spans the gap between the SS tubes that are attached to exhaust and the engine act as motion dampeners. I think you want that in place as the engine dog shakes upon startup, shutdown, as well as the vibrational effects. I addition, mine is old school design of the ball joint with springs to take up additional movement and heat expansion.
