Product Description

 

 

The Akrapovič Slip-On Line Titanium Exhaust System for the BMW M5 G90 (sedan) and G99 (touring) is a premium performance exhaust upgrade that dramatically enhances exhaust tone, reduces weight, and improves flow over the factory system. Precision-crafted from high-grade titanium with carbon-fiber/titanium tailpipes, this exhaust delivers a deep, athletic sound and measurable performance gains while retaining the factory valve-control functionality for refined acoustics in all driving modes. Akrapovič’s engineering ensures smooth integration with BMW’s electronics without requiring ECU remapping.

Fitment Notes

  • Designed specifically for BMW M5 G90 and M5 G99 models (S68 4.4L twin-turbo V8) — 2024 and newer. 

  • Compatible with GPF/OPF-equipped vehicles using the homologated Slip-On Line version (S-BM/T/37H).

  • Simple plug-and-play installation at the rear section with cutting of the stock exhaust; no ECU remapping required for the Slip-On Line system. 

  • Choose carbon/titanium tailpipe finishes (hexagonal or round) to suit visual preferences. 

  • Optional accessories (sold separately) may affect emissions compliance: carbon rear diffuser, carbon rear lip, link pipes, and sound kit.

Included

  • Titanium Slip-On Line exhaust system rear section designed for G90/G99 M5 

  • Exhaust valve control integration kit

  • Mounting hardware for direct fitment & installation instructions

Product Specs

  • Material: High-grade titanium for optimum strength, weight savings, and thermal resistance

  • Tailpipes: Carbon-fiber outer sleeves with titanium cores; hexagonal or round options

  • Weight Savings: ~31.8% lighter than stock rear exhaust section (~6.1 kg / 13.4 lb saved)

  • Compatibility: Works with gasoline particulate filter (GPF/OPF) systems 

  • Valve Control: Retains and enhances sound across all drive modes via OEM electronic actuators

Product Features

  • Significant Weight Reduction: Lightweight titanium construction trims mass from the rear exhaust, aiding responsiveness and reducing unsprung load.

  • Improved Sound Character: Tuned valves and acoustic reflectors provide a richer, deeper exhaust note that feels aggressive without excessive drone. 

  • Performance Gains: Tested gains of up to ~+7.1 hp and +24.3 Nm torque over the stock exhaust at ~2,050 rpm. 

  • OEM-Style Control Integration: Retains the M5’s factory exhaust valve control across drive modes for refined sound management. 

  • Carbon/Titanium Styling: Selectable tailpipes offer a sharp, bespoke finish that elevates rear aesthetics.

  • Plug-and-Play Design: Designed to work with OEM hanger points and electronics — no remap required for the basic slip-on install.
