ACAT’s proprietary metallic substrate technology is unique in the market offering an alternative to the me too standard ceramic substrates used by everyone else. HB stands for HerringBone pattern, which is at the core of every ACAT metallic catalytic converter. Our HB pattern substrates create a turbulent exhaust flow continuously breaking the boundary layer effect used by all ceramic substrates. Resulting in better flow, more poser, cleaner emission and better fuel economy under normal driving conditions.
