The Remus non-resonated cat-back front section pipe is made for 2018+ BMW M5 (F90) and M8 Gran Coupe (F93) with the 4.4L V8 S63B44B engine. As the front section of a cat-back system, this pipe replaces the factory front section to support free-flowing exhaust performance while fitting the specified BMW models and engine code without the factory resonator.
