In this video I show you how to remove the CAT on a BMW F30 3 Series to replac it with a CATLESS Down pipe. Please keep in mind installing a CATLESS down pipe will make your vehicle non street legal (Make sure to check with your local laws and regulations.)
Replacing the CAT with a downpipe increased performance and sound.
