Fitment Universal Metallic Catalytic Converter

ACAT Global’s EPA compliant Fitment Universal Metallic Catalytic Converters, with metallic herringbone monolith substrates, are engineered to improve power output and deliver OEM-quality durability, form, fit and function. Built for the automotive aftermarket, our metallic herringbone monolith design reduces back pressure and improves exhaust gas flow distribution for better performance and dyno-proven horsepower gains.

Our metallic converters also allow you to meet the strictest emissions standards while providing an opportunity to enhance MPG, reduce total system weight and noise, improve power output and decrease vibration and harshness.

Laser Precision


Every CNC-formed ACAT catalytic converter body is manufactured from a single laser-welded stainless-steel tubular section that is spun around ACAT’s herringbone metallic monolith.

Our herringbone substrates are wrapped with 3M Interam 1600HTE series non-intumescent mat-mount material, which lowers the outside converter shell temperature up to 400°F.

Perfect Fitment


Our Fitment Universal Metallic Catalytic Converters are specifically engineered for your vehicle based on its year, make and model. You can purchase our Fitment Universal converters with the confidence that it will fit into your vehicle – even if you don’t know your existing converter’s size, shape, engine displacement, etc. These converters often come with inlet/outlet extension pipes and I/O pipe diameters that require welding into the OEM system.

ACAT Global’s products are proudly made in the USA and Canada and backed by our limited lifetime warranty.
