ACAT Universal Fit Catalytic Converter Metallic Core EPA 10" OAL, 3.0" I/O, 5.9L

ACAT HB™ Made in the USA! Unique in the market, HB™ stands for HerringBone pattern, which is at the core of every ACAT HB™ metallic substrate catalytic converter. Using an entirely different construction, our metallic core converters allow exhaust gases to intermix and flow effortlessly through the whole substrate, Unlike traditional restrictive ceramic core converters that use single channel cell patterns. Our HB™ pattern creates a turbulent exhaust flow continuously breaking the boundary layer effect used by all ceramic substrates. Designed specifically for exhaust gas velocities encountered in today’s engine architectures, our ACAT HB™ solution is meant as a plug and play advantage resulting in better air flow for more power and less restriction for improved fuel economy (under normal driving conditions). ACAT Global Catalytic Converter Systems are manufactured in USA & Canada and backed by our limited lifetime warranty
