HJS Sports Catalytic Converters

The HJS Euro 6 high-flow catalytic converters offer optimal exhaust gas flow with minimal back pressure, resulting in higher power and faster turbo response.
The unique construction also ensures that the catalytic converters remain compatible with EOBD systems and meet the requirements for MOT inspections.

Advantages of HJS catalytic converters:

• More power due to lower back pressure

• No error codes or malfunctions in the engine management system

• Durable, heat-resistant, and emission-friendly

Thermo Heatshield Technology

These downpipes are equipped with JMTuning Thermo Heatshield technology, consisting of a double heat layer:

• An outer layer of stainless steel heat shield

• A core of temperature-resistant insulation wool

This construction prevents excessive heat radiation in the engine bay and significantly protects surrounding components better than conventional single-wall heat shields.
Please note: slight smoke may occur the first time it reaches operating temperature – this is normal and will disappear after a few minutes.

Perfect Fit and Installation

The JMTuning downpipes are designed as a complete OEM replacement for the original Porsche 992 Turbo S downpipes.

• Directly interchangeable with original parts

• Installation without modifications

• Perfect alignment with the original exhaust system
