Finally got the motor running, but I have an exhaust leak. The exhaust pipe "bell mouth" at the end does not line up (cuve up high enough) to completely seal. The exhaust manifolds are stock and this one on the left side has the steel donut molded into it. Is there a easy way to fix this this without taking the exhaust apart? The leak is very small, but I can still hear it.
Also, is it safe to run? I know with a snowmobile it could blow up with a leak like this.

A guy this weekend told me to use the red silicone on it. You think this will work?

I don't think any silicon will seal. Exhaust systems never seal correctly unless they are fitted perfectly. You just have to get the pipe to fit up to the manifold.

I don't think you're in danger of doing any damage, a lot of poeple run open headers with no trouble.

Hi temp silicone will do more than you think. I had a bad laek do to badly surfaced headers(schoefield 186's) tried double gaskets and nothing worked, put a small amount of high temp silicone and never leaked since. Dont know how but it works.

so is an exhaust leak sound like a ticking noise? I've got a ticking noise coming out of one side. Its goes away when the engine revs. I changed out the manifold gasket but its still there. Thinking its at the joint then.
