exhaust leak

[yamyrider]

I have a slight leak on two of the pipes right between the flange and pipe.
What is the best way to seal this. Should I be worries about sealing.

Where the donuts are?

I got the Aaen pipes used and there are none???
The pipes fit pretty tight over the flange...does any one know if these pipes should have something over the flange before installing pipes.

any ideas anyone....I am trying to finish the sled.
Should I have a doughnut or can I put exhaust seal.

idk if there is supposed to be a doghnut or not
if they fit pretty tight, chances are there isnt
i would use some red silicone, permatex brand, and make sure you let it set up fully before you try and ride it, otherwise you will just end up blowign the silicone out
