Remus Exhaust X-Pipe X Crossover & Link Pipes for BMW M3 F80 + M4 F82 (S55) – 70mm Stainless Midpipe/Mid-Pipe, Resonated or Non-Resonated, Centre/Center Cat-Back Middle Section – M3/M4 Competition Fitment | Resonator Delete Option

Remus X Crossover and Centre Link Pipes for BMW F80 M3 and F82 M4

Unlock a richer soundtrack and improved gas flow on your S55 twin‑turbo straight six with this premium Remus centre run. The X crossover and connection pipes replace the factory front silencer and secondary catalysts with a freer‑flowing 70 mm stainless system that delivers a deeper tone, sharper turbo whistle and a true motorsport character on your F80 M3 or F82 M4, including Competition models.

Factory bore is 65 mm. Remus upgrades this to 70 mm, allowing the engine to breathe more efficiently while maintaining the refined, high‑quality acoustics Remus is known for.
