Remus 089016 1500 089116 0300 0426 70SGR Resonated Cat-Back Exhaust System with Chrome Tail Pipes

The Remus 089016 1500 + 089116 0300 + 0426 70SGR is a complete resonated cat-back exhaust system engineered for the BMW M140i (F20/F21) with B58B30 engine, featuring integrated exhaust valves and a dual stainless steel chrome tail pipe set. Designed to work seamlessly downstream of the factory catalytic converter, this system delivers a meaningful improvement in power, torque, and exhaust note without requiring any ECU modification or rear skirt alteration.

System Configuration:

• 089016 1500 — Valved axle-back section with integrated valve, OE-compatible valve actuation via vehicle onboard electronics
• 089116 0300 — Resonated center section (EC homologation compliant)
• 0426 70SGR — Stainless steel tail pipe set: 2 tail pipes Ø 102 mm, angled (shorter length 145 mm), straight cut, chromed finish, with adjustable spherical clamp connection

Performance & Construction Features:

• Upgraded tube diameter: stock Ø 80 mm → Remus Ø 84 mm for reduced back pressure and optimized flow
• 100% stainless steel construction with shot-blasted surface finish
• Lightweight design — reduces overall exhaust system weight versus OEM
• Handmade in Austria to exacting quality standards
• TÜV approved; EC homologated (when paired with resonated center section 089116 0300)
• Exhaust valve activated by original OE actuator — no additional wiring or hardware needed
• No rear bumper or skirt modifications required

Important Notes:

• EC homologation is not valid when combined with the racing (pipe-only) front section 089016 0000 — homologation applies only with the resonated center section (089116 0300)
• The original OEM exhaust must be cut during installation

Backed by Remus's 24-month warranty, this cat-back system is an ideal upgrade for enthusiasts seeking a genuine performance and acoustic improvement while retaining full OE valve functionality and road-legal compliance.
