Experience Enhanced Performance with the Akrapovic BMW 340i (F30, F31) Evolution Line MTP-BM/SS/2H
Elevate your BMW 340i driving experience with the Akrapovic BMW 340i (F30, F31) Evolution Line MTP-BM/SS/2H exhaust system. Precision-engineered using austenitic stainless steel, this Evolution Line replaces factory components from the catalytic converters back, unlocking increased power, reduced weight, and a captivating exhaust note. Perfect for enthusiasts seeking a refined yet aggressive edge, the Akrapovic system comes complete with carbon fibre tailpipes that accentuate the 3 Series’ sporty character.
Important: This exhaust system is split into two part numbers—MTP-BM/SS/2H and E-BM/SS/2—which must both be ordered due to packaging constraints. Also note that it does not fit vehicles equipped with an Otto Particulate Filter (OPF).
Stainless Steel Construction for Lasting Quality
At the core of this Evolution Line lies Akrapovic’s commitment to superior build quality. The use of austenitic stainless steel ensures excellent resistance to heat and corrosion—ideal for spirited driving and track days alike. By opting for a dual-pipe layout instead of the single stock pipe, Akrapovič optimizes exhaust flow to minimize back pressure and enhance power delivery. The cat-back design is straightforward to install, typically taking around 120 minutes for a skilled workshop or an experienced DIY enthusiast.
Noticeable Power Gains and Torque Boost
When tested on Akrapovič’s in-house dyno, the BMW 340i (F30, F31) Evolution Line MTP-BM/SS/2H demonstrated real performance improvements over the stock system:
- Power Increase: Up to +2.9 kW / +4.0 HP
- Torque Gain: Up to +6.3 Nm
- Weight Reduction: Approximately 0.8 kg (a 3.8% decrease)
While the weight savings may appear modest, every kilogram matters for overall vehicle dynamics. Combined with the added power and torque, these improvements bolster mid-range acceleration and deliver a more engaging driving experience—whether you’re navigating busy streets or enjoying a spirited countryside run.
Dual-Mode Exhaust Valve for Versatile Sound of Akrapovic BMW 340i (F30, F31) Evolution Line MTP-BM/SS/2H
A standout feature of this Evolution Line is the dual-mode ECU-controlled valve. By default, the exhaust remains civil during light cruising, offering minimal drone and an understated tone that aligns with day-to-day commuting. Under spirited acceleration, the valve opens to unleash a deeper, more aggressive exhaust note, reflecting the six-cylinder engine’s true capabilities. This dual personality ensures you can enjoy refined comfort for errands and a track-ready soundtrack when pushing your 340i to its limits.
Carbon Fibre Tailpipes for a Finishing Touch
The carbon fibre tailpipes anchor the Evolution Line’s sporty aesthetic. Designed to withstand high temperatures and maintain a sleek appearance over time, each tailpipe seamlessly blends with the 3 Series’ rear bumper. Carbon fibre’s motorsport pedigree not only adds visual appeal but also underscores Akrapovič’s dedication to using cutting-edge materials. The result is a refined look that leaves no doubt about the vehicle’s upgraded performance credentials.
Cat-Back Design for Simpler Installation of Akrapovic BMW 340i (F30, F31) Evolution Line MTP-BM/SS/2H
Because this system replaces only the stock exhaust from the catalytic converters back, there’s no need to alter the vehicle’s emission-critical components. That means:
- Straightforward Installation: The process is largely bolt-on, and you can revert to stock if desired.
- Minimal Impact on Emissions: Retaining the catalytic converters helps ensure the car remains emissions-compliant in regions that do not mandate an OPF for this model year and variant.
- Preserves Driveability: By maintaining the OEM catalytic converters, you keep the factory tune intact, avoiding potential check-engine lights or the need for complex engine remaps.
Not for OPF-Equipped Models
It’s essential to note that this exhaust system is not compatible with vehicles fitted with an Otto Particulate Filter (OPF). If your 340i is equipped with an OPF, you must seek an alternative exhaust solution designed to accommodate that specific hardware. Using a non-OPF exhaust on an OPF-equipped car may cause fitment or emissions issues.
