CARGRAPHIC / HJS sport catalytic converters and cat-replacement pipes for Audi Q7 4L 4,2l V8 FSI

High-performance sports catalytic converters provide more power and sound for the Audi Q7 4L 4,2l V8 FSI

For the Audi Q7 4L models with 4,2l 8-cylinder engines, the CARGRAPHIC Sport catalytic converters offer a much more efficient exhaust gas flow compared to the standard components and a noticeable increase in performance. In addition, the typical Porsche sound is significantly increased and provides an enhanced emotional driving experience.

High-quality T38 coating with 4 times the amount of precious metals

CARGRAPHIC catalytic converters have a honeycomb body in HD matrix design, which is covered with a much higher quality T38 coating than conventional sports catalytic converters. This means almost 4 times the amount of precious metals, consisting of platinum, palladium and rhodium.
As a result, CARGRAPHIC catalytic converters have a better cleaning effect than more closely meshed systems with a lower quality coating.

Honeycomb structure in HD-Matrix design and radial groove

HD-Matrix stands for High-Durability and characterizes the honeycomb structure designed for maximum durability. The radial groove in the shell reliably prevents any movement of the honeycomb body under high exhaust gas pressure, thereby supporting its durability. Together with its T38 tri-metal coating developed exclusively for CARGRAPHIC, the CARGRAPHIC catalytic converter ensures exhaust emission values at vehicle manufacturer level, with a simultaneously increased throughput capacity and a significantly lower exhaust back pressure.
