144 x 100mm Ceramic Honeycomb DOC For Diesel Vehicles Exhaust Converter
This 144 × 100mm Diesel Oxidation Catalyst (DOC) provides targeted exhaust treatment for light and heavy-duty diesel engines. Built around a 400 CPSI cordierite ceramic honeycomb core, the unit continuously oxidizes toxic carbon monoxide and unburned hydrocarbons into safe carbon dioxide and water vapor. By pre-treating the exhaust stream, it decreases particulate buildup, stabilizes NO/NO2 ratios, and prepares downstream DPF and SCR modules to operate at peak efficiency. This universal catalyst helps modern diesel platforms comply with Euro 5/6, Stage IV, and Tier 4 interim/final emission regulations without requiring liquid dosing or operator intervention.
Benefits & Practical Tips
- Extend DPF Lifespan: Running exhaust through this DOC first promotes passive ash burning and cuts the frequency of regeneration cycles.
- Streamline Exhaust Layouts: The open 144mm diameter and optimized flow path often allow shop fabricators to drop factory mufflers while maintaining correct backpressure.
- Confirm Mount Spacing: Measure your chassis pipe centers against the 100mm cylindrical length before cutting; custom flanges or hangers are frequently needed for accurate fitment.

Installation Reminders
Secure all weld points thoroughly during fabrication to prevent exhaust separation under vibration. The manufacturer does not accept responsibility for damages caused by loose seams, improper gasket seating, or incorrect mounting angles. Verify thread alignment and thermal clearance before finalizing the exhaust system.
