If you do replace it correctly, it will work as designed.
If the leak is against the head, it can burn tracks into the exhaust port faces as if done by a cutting torch.
Advanced timing can cause that to happen
It would be a waste of time and money. You would have to make a special adapter to hook the exhaust to the manifold. On a turbo header, the exhaust hooks to the turbo and the turbo to the manifold.
Engine would get far too much air and it would never run correctly.
Exhaust Heat happened in 1992.
Yes, it could. What could happen is it leaks as you are going down the road and leaks onto the exhaust manifold and creates the smoke.
Dont laugh when i ask this but I seen it happen before, Is there gas in the tank?
yush
Do you have an exhaust leak? Do you happen to have have an exhaust leak or a damaged water pump bearing?
we have no structures correctly
There are too many reasons this can happen to be positive, however the most common reason is the exhaust pipe is not snug, or bad gasket at the manifold. Where it bolts to the cylinder. If it is not that, you will need a harley mechanic to look at it.
exhaust will be smoky. exhaust temperature will be high
