I just removed the stock 2 into 1 exhaust from my 2010 FLHX and changed to a stock 2-1-2 head pipe with LA choppers slip-ons. My problem is now i feel a slight vibration in my floor boards that I don't remember being there before. Any thoughts ??

 

I'd double check all the fasteners and mounts .... but ... it's not uncommon to pick up minor vibrations when replacing exhaust .... harmonics!

 

yes, check for binding rubber mounts on the mufflers

In addition to all of the other suggestions, inspect every inch of the header and heat shields (don't forget the heat shield camps) to make sure that there is NO contact between the header, the heat shields or the heat shield clamps, with any part of the frame. It doesn't take much to cause an added vibration if things make contact. That vibration gets transmitted from the header to the frame and, well, there you go.

 

Probably just more vibes from harmonics. Picked up more vibes when I added Monster Ovals, and a little more after the Andrews 21 cams.

 

Thanks for input, I will check to make sure everything is clear and if so , figure it's just harmonics

 

Had this happen on my 08 SG and my 2012 Ultra. Check the clearance between the rear brake lever (where it connects to the brake rod) and the header.

 

How do you fix the clearance issue? I just put a 2:1 on mine and have the vibration and found this thread. Look on mine and the rear break lever is pushed up hard against the pipe...
