Akrapovič Evolution Link Pipe Set (SS) – BMW M135i (F40) – 2020 – OPF/GPF

Article number: E-BM/SS/6

The Akrapovič Evolution Link Pipe Set (SS) for the BMW M135i (F40) is the ideal upgrade for enthusiasts who want to unlock their BMW's full potential. This stainless steel link pipe set was developed in conjunction with the Akrapovič Slip-On Line (Titanium) and replaces the restrictive OPF units, significantly improving both performance and sound.

The optimized gas flow results in a more direct response, more power, and a sportier sound that matches the M135i's character. Removing the OPF creates a fuller, more intense sound with characteristic cracks and burbles during throttle lift-off and downshifts – an auditory sensation impossible with the standard exhaust system.

This upgrade is designed for closed track use only, and requires ECU remapping to prevent error codes.

Key Features

• High-quality stainless steel Evolution Link Pipe Set (SS)
• Developed in conjunction with the Akrapovič Slip-On Line (Titanium)
• OPF-delete for maximum gas flow and performance
• Significant sound improvement with a sportier, more aggressive character
• More cracks and burbles on throttle lift-off and downshifts
• Clearly noticeable power and torque increase
• Reduction of backpressure for quicker response
• Lightweight design: –3.5 kg compared to original
• Perfect OEM fit and high-quality finish
• Designed for track use (closed course only)
• Tested on the Akrapovič dyno with back-to-back comparisons

Performance Gains

• +5.1 kW (+6.9 hp) at 4250 rpm

• Weight: –3.5 kg

The performance improvements are clearly noticeable and have been confirmed by dyno measurements comparing the BMW M135i with the standard exhaust and with the Akrapovič system directly. The system allows the engine to breathe more freely, resulting in improved turbo response and more powerful midrange performance.
