I have a 2009 Dodge Ram 2500 5.7L, and was wondering if these headers (Flowtech 91950FLT) fit my truck. I know in the description it say it does. I have shopped around and other manufacturers carry headers for the 1500, but not the 2500. Some say there are issues with motor mount clearance. The Flowtech headers do not specify 1500, 2500, 3500. Do these fit?
