More power, less backpressure! Autodelta has chosen HJS Motorsport Catalysers (Germany). HJS is the leading manufacturer of motor sport-catalytic converters in Europe.

All manufacturer involved in Motorsport rely on Cat-technology from HJS Motorsport. Their unique experience and the continuous development guarantee products of high quality and competitiveness. .

In cooperation with the DMSB and the FIA, HJS has developed a concept which allows them to offer the right catalytic converter for all possible application cases in motor sport. For the technical regulations of the FORMULAR 3, the International and national Touring Car series and the WORLD RALLYE CARS and KIT CARS HJS has developed specific catalytic converters which also have a FIA homologation. For all the other technical regulations there is the HJS standard motor sport-catalytic converter programme which follows the cubic capacity classes of competition vehicles. Through this it is guaranteed that for all current automobile racing series the right catalytic converters are available. .

We have extensively tested and have chosen a HJS Motorsport unit for our most extreme tuned conversions to achieve maximum flow and less backpressure resulting in more power, couple this with increased engine performance and throttle response. These units have been tested and are running in Autodelta tuned cars with over 400bp while keeping OBD operation and MOT emissions in place. These Motorsport catalyser are characterized by 30% less weight in relation to the OE parts.

Made in 304 Stainless steel and CNC bend tubing ensure a perfect fit.
