The RECORE™ process is a patented technology where we remove the old core of your DPF, DOC, SCR, or CNG and replace it with a new, quality standard core while preserving your original shell. Unlike traditional replacement that requires purchasing an entirely new unit, RECORE™ provides like-new performance at a fraction of the cost by only replacing the internal components that have deteriorated. This innovative approach guarantees a perfect fit since we use your existing housing, eliminates compatibility issues, and comes with a comprehensive 3-year warranty that exceeds industry standards.
