Torque is a measure of rotational force around a point, in this case caused by gravity. That's what I meant...though I kind of had the same thought as you after I typed it.

edit: Here ya go:

I talked to the seller. He told me he had never had them mounted on a car, and that they looked a-ok to him when he sold them to me.

That's a huge amount rust for a stainless pipe. I thought the SSIs didn't rust. Does that look unusual to anyone else?

ditto....thats not stainless or at least not from my point of view.but i like the word gravitational torque and the man does have a nice car so hes good....OK im go`n home later fella`s

I wish I had the pictures from Brad's shop. (IMG:style_emoticons/default/dry.gif) Looks close to what you show here. These were not stress cracks.

I've been wondering if mine leak since I first saw this thread. I just re-finished the mating ends and used new gaskets. Still getting the slightest little pops out the exhaust on decel.

This was obviously not a split at the seam formed when the pipe was rolled. I'm having a hard time wrapping my mind around how this could happen. (IMG:style_emoticons/default/blink.gif) That crack goes 270 degrees around the circumference of the pipe.


stress crack ... maybe the car was run without a muffler hanger for a extended period of time ...

Take a magnet to the section of pipe that was cut out.

Tell us if it sticks.

A neighbor of mine looked at my new SSI's and said....

They're gonna rust...

He is an aerospace metalurgist for GE aircraft engines and told me the SS tubing grade is non-magnetic and will rust. Not as much as steel , but it will...

As per the one in pieces, explosions down the exhaust will do that..... My POS honduh used to periodically do that and either blew out one of the bends in the pipes or sent the guts of the muffler shooting about 60 feet out the rear of the car..... That's 3 factory exhausts in 70 k miles and loads of excitement for people following me.....

That crack all around looks like a combo of rust and fatigue....

If I have my information right from Brad, he too spoke with metalurgist. Something about the tubing taking longer to cool and water (moister) collecting in there that will cause them to rust. While they are better than stock exchangers they do need to be checked.

I would think a easy pressure test should tell you if you have a leak in them or not. Plug one end with some sort of rubber plug, the other end the same with and air in let and listen for leaking air? (IMG:style_emoticons/default/confused24.gif)

...that's exactly how the shop determine mine had a leak.

This has been an interesting thread. It seems like there's a widely held misconception that SSIs *will not* rust, and all of a sudden plenty of evidence to the contrary. I will admit that I didn't think they would rust, and was initially skeptical when told mine was leaking...because everything I'd read seemed to indicate SSIs are, loosely, "bulletproof".

Thanks everyone for your feedback. Gotta love this place. (IMG:style_emoticons/default/beerchug.gif)

If your SSI's have cracks anything like that THEY ARE JUNK AND SHOULD BE THROWN OUT!!!!! If you weld patches inside the heat collectors you could kill yourself!!! There shouldn't be any welds inside the heat collectors. Porsche found this out back in the 60's after a customer or two DIED from CO1 poisoning. The money you saved will be useless if you are dead.

As an "informed" group, I believe we have a responsibility to the 914 community to share critical life-safety information.

If the above is agreed upon by us, how can we dissiminate this information before someone gets seriously sick/dies from the use of a dangerous SSI?

My concern echoes the above posting. The SSI is pumping air into the cabin. If there is any chance of CO1 getting this loop, we need to take some educational actions. (IMG:style_emoticons/default/WTF.gif)

There is a product for small aircraft, most of which also use manifold heat.

More info on how serious this really is.

FWIW the factory used a form of stainless tubing with mild steel heater boxes, so the boxes would rust before the tubing.

The oem tubing was also much heavier wall thickness and could easily withstand the pressure of backfires.

T304 stainless is very corrosion resistant at temps up to about 800F. When it is kept above 900 deg. for an extended time period changes take place within the grain structure that dramatically reduce the anti-corrosion properties.
The technical term is carbide precipitation.
