This auction is for a pair of Rinehart Racing Catalyst Baffles for your 4" Rinehart Slip-On Mufflers (with 3 hole mounting style on backside of your end caps) 

These are normally sent along with the Rinehart Header Kits (which do not have a Catalyst) to make your system compliant with State Regulations. If you have a head pipe with Catalyst already in it, then these are NOT for you. These are for use with head pipe systems without a catalyst. 

New in box. See all photos.
