When I removed the V&H exhausts (which were working fine) on my FXD there weren't any gaskets, I did however notice a tacky silicone where the gasket would have been, I think! When I replaced the exhaust I used the standard wire wool type exhaust gasket but don't seem to be able to tighten them up enough which seems to be the cause of popping and backfiring etc on deceleration. I have tightened the exhaust bolts up as much as I feel is safe to do so but it doesn't seem enough and I don't want to force anything over and beyond!
Is there a silicone that can be used in place of the standard gasket or are the wire wool gaskets the only option. On a sportster I owned in the past I used copper ring crush gaskets which worked well, would these be ok for a 99 FXD?
