Emission control: HOT END PRODUCTS
In emission control, the right repair does more than restore performance. It protects compliance, workshop credibility and day-to-day vehicle reliability.
That is why DRiV’s Walker® hot end products are engineered in Europe and homologated in line with applicable European requirements. From catalytic converters to DPF, SCR and GPF technologies, every solution is developed to support the demands of today’s highly regulated emissions systems with precise fit and reliable function.
Designed to help technicians complete repairs with confidence, Walker combines advanced emissions expertise with aftermarket-focused innovation to support professional repairs across evolving vehicle technologies.
HOT END RANGE - FULLY HOMOLOGATED
Walker hot end products are homologated in line with applicable European regulatory standards and requirements. From catalytic converters to DPF, SCR and GPF technologies, each solution is developed and validated to support aftermarket repairs across modern vehicle applications.
For workshops, homologation helps reduce the risk of installation issues, warning lights and performance-related concerns that can impact customer trust and workshop credibility. For technicians, it provides confidence that the replacement part is designed to perform as intended within the vehicle’s emission system.
CATALYTIC CONVERTERS
Designed to help reduce harmful exhaust emissions and support vehicle operation across a wide range of applications in line with applicable emissions requirements.
DIESEL PARTICULATE FILTERS (DPF)
Designed to capture soot from diesel exhaust and support emissions requirements over the service life of the vehicle.
GASOLINE PARTICULATE FILTERS (GPF)
Developed for modern gasoline direct injection engines, GPFs capture fine particles before they leave the exhaust system. They regenerate more easily than diesel particulate filters and are less prone to clogging.
SELECTIVE CATALYTIC REDUCTION (SCR)
SCR systems help reduce NOx emissions in diesel applications, supporting cleaner operation and alignment with European standards.

FREQUENTLY ASKED QUESTIONS
Common signs of a failing hot end component, such as a diesel particulate filter (DPF), catalytic converter, or diesel oxidation catalyst (DOC), include reduced engine performance, increased fuel consumption, loss of power, warning lights on the dashboard, excessive exhaust smoke, or repeated regeneration issues. Prompt diagnosis and replacement can help restore vehicle efficiency and help prevent further damage to the emissions system.
Walker Hot End products are engineered to align with equipment (OE) standards for fit, performance, and durability. Designed with advanced emissions-control technology and precise vehicle coverage, Walker components help technicians complete reliable repairs while restoring emissions compliance, engine efficiency, and system performance over time.
Hot end components can fail due to soot and ash buildup, thermal damage, contamination from oil or coolant, faulty sensors, engine performance issues, or prolonged exposure to extreme operating conditions. Identifying and correcting the root cause of the failure is essential to support the service life of the replacement component.
Properly selected and installed hot end components can help support correct exhaust flow and emissions system operation. Where a restricted or damaged component is contributing to the issue, replacement may help reduce excessive backpressure and support drivability. The final result may depend on the condition of the overall engine and emissions system.
Technicians should inspect related components such as sensors, clamps, gaskets, mounting hardware, injectors, and exhaust piping when replacing a hot end component. Following the manufacturer's recommended diagnostic and installation procedures helps with a complete repair, reliable performance, and emissions system durability over time.
