Fast Intentions also has produced a line of factory Catalytic Converter replacements. These high performing CATS not only give you more power, but a deeper growl to the systems as well.
In both pictures - the left CAT is 400 cell ceramic and the right is 300 cell metallic
NOTE: The sound level of the metallic CATS will be slightly louder then the ceramic version.
400 Cell Ceramic CATS
An upgraded version of the O.E.M. cat, using a honeycomb style brick, which will clean and perform well with being slightly louder than its stock counterpart.
300 Cell Metallic CATS*
A metallic foil wrapped and heat treated for maximum durability. This cat will clean the best out of the two as well as produce even greater performance. Recommended for forced inducted applications.
