Elevate the performance and acoustic presence of your BMW M140i with the Akrapovic BMW M140i (F20, F21) Evolution Line MTP-BM/SS/3H exhaust system. Constructed from premium austenitic stainless steel, it delivers a refined blend of power gains, weight reduction, and captivating sound. Sporting hand-crafted carbon-fibre tailpipes, this system replaces the stock exhaust from the catalytic converters back, giving your M140i a balanced mix of everyday usability and track-inspired flair.

Ordering Note: To complete the Evolution Line system, you must order two part numbers—MTP-BM/SS/3H and E-BM/SS/3—due to packaging requirements.

Designed for More Power and Torque

Through meticulous engineering and testing, the Akrapovic BMW M140i (F20, F21) Evolution Line MTP-BM/SS/3H demonstrates tangible performance gains on Akrapovič’s in-house dyno:

• Maximum Power: up to +4.8 kW (+6.5 HP) at 5,500 rpm
• Torque Increase: up to +12.6 Nm at 3,000 rpm

These enhancements add up to stronger mid-range acceleration and more confident overtaking, ensuring your BMW M140i remains thoroughly engaging whether commuting or exploring winding country roads.

Weight Reduction for Improved Dynamics

Weight savings might seem minor at just 0.7 kg (1.6 lb), but every kilogram counts when optimizing handling. By shaving off around 3.3% of the factory exhaust’s mass, this Evolution Line setup helps you feel sharper turn-in response and a nimbler overall driving experience—particularly valuable on twisty roads or spirited track sessions.

High-Quality Stainless Steel Construction

At the heart of this exhaust is austenitic stainless steel, chosen for its durability, corrosion resistance, and ability to withstand extreme heat. Replacing the single stock-pipe layout, two central link pipes optimize exhaust flow, reducing back pressure and maximizing your M140i’s turbocharged engine potential. The streamlined tubing keeps exhaust gases moving freely while maintaining structural integrity, even under aggressive driving conditions.

Dual-Mode Valve for Versatile Sound of Akrapovic BMW M140i (F20, F21) Evolution Line MTP-BM/SS/3H

A centerpiece of the Akrapovic BMW M140i (F20, F21) Evolution Line MTP-BM/SS/3H design is its ECU-controlled dual-mode valve. When cruising at steady speeds, the exhaust remains discreet, minimizing drone inside the cabin and preserving comfort for daily use or longer road trips. However, once you press the accelerator and build revs, the valve opens to produce a deeper, more spirited note that showcases the 3.0-liter inline-six’s character. This dual personality gives you the best of both worlds: a refined ride or a sporty symphony on demand.

Carbon-Fibre Tailpipes: Form Meets Function

Completing the system are hand-crafted carbon-fibre tailpipes, which bring motorsport styling to your M140i’s rear profile. In addition to lending a distinctive visual appeal, carbon fibre provides outstanding heat resistance and durability, ensuring your exhaust retains its premium finish over the long haul. The tailpipes complement the car’s aggressive stance and highlight the performance pedigree of Akrapovič’s exhaust design.

Simple, Plug-and-Play Installation

The Evolution Line exhaust conveniently replaces your OEM setup from the catalytic converters back, often referred to as a cat-back configuration. This approach leaves the factory downpipe and catalytic converter intact, minimizing potential compatibility or emissions concerns. Installation typically takes around 150 minutes, making it a feasible project for a seasoned DIY enthusiast or a professional workshop. Once in place, the exhaust aligns with the BMW’s existing electronics to regulate the dual-mode valve seamlessly.

Fitment Notes and ECE Compliance

• X-Drive Compatibility: This system is compatible with xDrive variants of the F20/F21 M140i.
• No OPF Models: It does not fit vehicles equipped with an Otto Particulate Filter (OPF).
• ECE Approved: Thanks to its design and integration with the factory catalytic converters, this exhaust meets ECE regulations, ensuring it’s compliant where ECE standards apply.

Everyday Comfort and Track-Ready Thrills

Whether you’re navigating daily commutes, enjoying weekend getaways, or pushing limits at high speeds, the Akrapovic BMW M140i (F20, F21) Evolution Line MTP-BM/SS/3H adapts to your driving style. When the valve is closed, the cabin remains calm enough for everyday convenience. But as soon as you open the throttle, the exhaust roars to life—revealing a race-inspired edge that never fails to engage the enthusiast within. This flexibility makes the system an ideal upgrade for drivers who want a dynamic exhaust note without sacrificing comfort or practicality.
