FITS MUSTANG AND F150.

Did you purchase a set of 2M Fabrication Classic/Lone Star Headers or a set of Stainless Works headers and chose the catless option, but now are interested in putting in a set of high-flow metallic cats? These are your ticket. They are the same length as the straight mid-pipes that come with headers, so they will go right into the area after the headers and before the "s bend" mid-pipe.

These converters meet Federal US EPA standards. They are NOT legal for use on any vehicle licensed or operated in the state of California. Restrictions may also apply in states that have adopted all or parts of California emissions standards. Please check state and local laws for specific converter replacement requirements.
