OEM parts often times are designed for efficiency of manufacturing, cutting costs and driver comfort. Unfortunately performance is often not a priority – as seen on the very restrictive factory S197 Cat Back on the 4.6L Mustang GT motor.
 
LTH has developed a high-performance cat back exhaust system for the 4.6L motor found in the Ford Mustang GT.
 
Designed using the latest in CCM and CAD technology the cat back is a masterpiece. The end goal of aggressive sound along with drone-free cruising has been achieved with the LTH cat back.
