Secondary cat delete (138 EU4)
US spec & 2006-2007 EU
Our secondary cat delete, this version is designed for EU4 models (2006-2007) and all US-spec vehicles, this upgrade eliminates the restrictive "dent" in the factory exhaust system and removes the large secondary catalytic converters for enhanced performance.
The restrictive "dent" is replaced with a precisely stamped oval merger, ensuring optimal ground clearance and seamless flow, matching the surrounding pipe diameters. As a single-piece component, it reduces welding stress and minimizes weight, improving both durability and efficiency.
