Exhaust crush gaskets
 

When i bought my sportster the previous owner had pretty much tore out the baffles on the stock pipes... i was very unhappy with the sound so i replaced them with stocks temporarily. (Hey, they were free) The Rush pipes come in on Friday and those will probably be put on this weekend.
Now, i put new crush gaskets on the pipe to o2 sensor as required. However, with my new Rush's as new as the crush gaskets are is there any possibility i can recover them or do i need new ones?
If they are recoverable will i run into major exhaust leak issues?
Thanks for the help.

Is it really worth saving a few dollars to find out?

I bought new ones when I put my Rush pipes on 07 Sporty. I buggered them up when removing stock pipes. I like having a set on hand so you can complete the job w/o a trip to the dealer in event one gets ripped apart.

I didn't use new ones when I put stock pipes back on the Sporty before trading it in last week. :D

you don't need new ones. but they MIGHT LEAK. so replace them at a small cost instead of dealing with it again in the future.

I would replace them. If your luck is as good as mine, they will leak.
