The TTRS 8S with gasoline particulate filter (OPF) presented us with a complex technical challenge. The aim was to fully retain the incomparable emotion and performance of the predecessor model without OPF despite the stricter emissions regulations. Through innovative approaches in the exhaust system, precise software tuning and the targeted use of high-quality materials, we were able to achieve an optimum balance between performance, sound and environmental regulations. Our expertise in the field of exhaust construction and performance enhancement was decisive in this. All components - from the exhaust system and turbocharger to the control software - are manufactured and tested in-house in Germany. This complete control guarantees the highest quality, maximum stability and precise tuning that remains consistent even under extreme conditions. With the TTRS 8S OPF, we combine uncompromising performance with a genuine motorsport feel - made in Germany.
