I had some issues mounting the power duals to my '14 Limited. The tranny bracket did not line up properly. Didn't really know how much it was off until I took the bike for dyno tune and it showed an air leak at the head. I had to remove them and enlarge the tranny bracket hole to make them seat properly. Hope your install went better. I've installed dozens of pipes before, never had that happen.
Mine wasn't that bad. I did have to loosen the bracket at the tranny in order to get the holes on the pipe to line up. Trying to tighten them again with the pipe in place was a challenge.
