Remus 089016 1500 089116 0300 0426 70CSR Cat-Back Exhaust System with Carbon Tail Pipes Clutch Kit

The Remus 089016 1500 + 089116 0300 + 0426 70CSR is a resonated cat-back exhaust system engineered for the BMW M140i (F20/F21) 3.0L B58B30 engine (non-GPF/non-OPF models). Handcrafted in Austria by Remus — a globally recognized performance exhaust manufacturer — this system is designed to work seamlessly with the factory catalytic converter, requiring no ECU tune or rear skirt modifications.

This complete cat-back package includes three components: the axle-back section (089016 1500), the resonated front/center pipe (089116 0300), and the 0426 70CSR carbon fiber tail pipe set — delivering a refined, aggressive exhaust note with a premium visual finish.

Key Features:

• Carbon fiber tail pipes: Dual 102mm angled tips (shorter length 145mm) with titanium internals and adjustable spherical clamp connection
• Resonated center section (089116 0300): EC/TÜV homologated configuration for road-legal use
• Upgraded tubing: REMUS tube diameter Ø 84mm versus stock Ø 80mm for improved exhaust flow
• 100% stainless steel construction: Shot-blasted surface finish for durability and corrosion resistance
• Integrated exhaust valve: Activated by the original OEM actuator via the vehicle's onboard electronics — no modifications required
• Lightweight design: Reduced weight compared to the factory exhaust system
• EC homologation: Supplied with homologation documents when used with the resonated center section
• 24-month warranty from Remus

System Components Included:

• 089016 1500 — Axle-back section with integrated valve
• 089116 0300 — Resonated center/front pipe
• 0426 70CSR — Carbon tail pipe set (2 pipes, Ø 102mm, angled, titanium internals)

Reduced back pressure and optimized flow dynamics deliver a meaningful increase in power and torque while producing the signature, sonorous Remus exhaust tone. No rear bumper or skirt modifications are needed, making this a clean, direct-fit upgrade for the BMW M140i platform.
