Here something you should look into if you are going to install a Cat Back Exhaust on your S197. I already did my exhaust and did not know about this and it applies to me.
Now you can swap out your Mustang's exhaust hanger hardware for pure 304 Stainless Steel! These Mustang exhaust hangers feature OEM style construction but ditch the rust prone factory steel for 304 Stainless!
They work with any aftermarket or stock cat-back exhaust system and will be the last hangers your Mustang will ever need! This kit fits all 2005-2010 Mustang V8 and V6 and is also the required hardware for installing a True Dual GT Cat-Back on V6 Mustangs!
Applications:
2005-2010 Mustangs All V8 & V6
Required for 2005-2010 V6 with True Dual GT Cat Back Conversion
Required for mid-2007 Axle-Back & Cat-Back Installation*
* Sometime in 2007, Ford changed the style of exhaust hangers used to install the stock exhaust on the 2007 S197 Mustangs. They switched from a "rubber and steel" hanger design to an "all rubber" hanger, which will not work correctly with the after-market cat-back exhaust systems on the market today. Please visually check your exhaust to determine whether or not you need this optional rubber and steel hangar.
