Don’t just replace your defective cat — improve overall performance with ACAT.
The ACAT PRO series catalytic converters utilize our new exclusive metallic herringbone substrate technology for maximum efficiency. Unlike other so-called “Metallic Sport Cats” our metallic herringbone substrate design allows for lower cells per square inch, which improves flow and reduces back pressure for better overall performance and dyno-proven horsepower gains. This also translates to better fuel economy! And with the exhaust gasses passing through our exclusive herringbone design, significant improvements in lowering emissions have been documented. The ACAT PRO efficiency doesn’t stop here – it allows for a smaller, more compact and lighter weight catalytic converter. Every ACAT PRO catalytic converter body is manufactured from a single CNC-formed laser-welded stainless steel tubular section that is spun around ACAT’s exclusive herringbone metallic monolith. And thanks to our exclusive 3M™ Interam® 1600HTE series non-intumescent mat-mount material, the outside temperature is lowered by 300℉ to 400℉. Made in USA/Canada to the highest quality standards utilizing the latest in catalytic converter manufacturing technology and backed by our limited lifetime warranty.
The result – more power, improved fuel economy, OEM durability and reduced emissions.
