Yep, mine interfers with the hanger under the driver's side rear door. The exhaust shop that put it in just slid the rubber hanger over and it will fit. The only problem is that there is contact. This causes to vibrations that normally would be isolated from the cabin to transfer through. The SFC fit but the noise is an irritant. I plan on seeing what it would take to move that hanger or I will be wrapping that small section of the sfc with rubber to try and insulate it.
