Been running my V&H slip-ons for about 200 miles now and love them. The other day I had the bike up on a lift doing some cleaning and noticed underneath where the mufflers slip-on to the header there was a lot of black residue. I double checked the tightness off the exhaust clamps that were provided by V&H with my new pipes and they seemed fine. When I start the bike up I definitely can feel a leak on both sides. I guess I should run the bike and heat up the pipes to see if they seal up. They seem to be seated fine. Anyone else experience this with their V&H with slip-ons? Thanks in advance!
