3) Due to the amount of lateral and medial flex of a rubber mounted motor, you need some element of flex in the exhaust. Another method may be the wire mesh flex pipes they use on transversely mounted front wheel drive cars.
yup makes sence how about just like the two strokes with a gasket and springs????

Different animal because on the two strokes the exhaust doesn't run down the tunnel and exit out the back... thus, little flex to account for!

just be happen its not the snopro 500 they catch on fire. One stared a fire after he had engine trubs and cam up an then, then his oil lit on fire and went all over the place. Then one burned down in a race.

What happened to the first one?

The first one came in shortly after I wrerked, becaues he was having problem. He got back to staging and his motor lit on fire then, oil started on fire and was oil over the ground. The second one was the same thing but ferther into the race. Shortley after the first one was in flames some guy was being interview and saying how the snopro 500 are bullet prof and he 1,000 mi on the sled without any problem, and never touched it.

1) When an individual (not a group) directs a statement " wonder how long before a mod deletes this post" toward my correct post, I tend to get a little edgy. However, in keeping with the true spirit of why we are here-------------I do offer my sincere apologizes. And yes, I do like the support of the group as a whole.
2) Speaking of my correct post, perhaps it wasn't. I did not understand the rules governing vendors vs. advertisers. I truly meant no disrespect towards any vendors to whom support this site. Thinking positive, why not contact Dan Swain and ask if he would advertise on this site. For the record, I do not sell nor in anyway represent his company.
3) Great point and knowing one of the weak points in the exhaust system, perhaps us Phazer owners can turn to a REAL engineering guru. Cannondale-----can you say Aaen?
I would ask Aaen but I dont know what the issue is?I have heard of a few turbo guys breaking the flex pipes but us non turbo guys dont seem to have that issue.Our issue is just the pipes breaking off at the manifold.Corrected by welding,donuts loosening and leaking.Corrected by grinding a little off the spacer and tightening good,Heatshields falling apart after 3 years use.Corrected by replacing.All the ceramic coatings are real nice and would help heat but would not correct any of those issues.Closing off the tunnel I believe helps alot of the breakage because giant ice chunks dont slam the exhaust anymore.Rotax454 let me know what I should ask.

settle down boys - it looked a lot like the fast airwave thread and the infamous barker exhaust post that got dp'd. you posted a new topic for a problem that i frankly have not come across with a direct link to a product. if the mods don't see anything wrong with it then i don't give a #*$&@ about it either.

All great points. Just getting the entire exhaust system removed from the sled. Will examine and get back to you. Initial inspection shows fateage area in the heat pad. My experience with that asbestose type material is-------junk. Heat and weather breaks down that material quickly. Basically is old school. Much better and affordable alternatives today to heat shielding. Keep in mind too, my sled only has under 500 miles on her. I have other sleds to ride for one, and I simply work wayyyyyyyyyyyy to much. Chasing the mighty dollar.

Some of the heat shield material on mine had come off because of a loose clamp rubbing it. Someone hadn't tightened it to spec and it fell off 
I didn't replace the heat shield as I saw no signs of overheating in any place regarding the tank.
The reason I luckily discovered this was that I was going to replace bad heat wrapping that had disintegrated and clogged the air filter.
The engine hadn't run very good for some time.
Now it's a completely different power experience
Now it looks like this
