Direct Fit Universal Metallic Catalytic Converter

ACAT Global’s EPA compliant Direct Fit 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 – at a competitive cost.


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.

Designed To Fit


Our Direct Fit Universal Metallic Catalytic Converters are typically designed with flanges to allow you to bolt the converter directly to your vehicle’s OEM exhaust system architecture.  Some Direct Fit Systems, also referred to as Semi-Fit Converters, may also be bolt or slip/clamp mounted to your exhaust system.

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