Akrapovič BMW 340i/440i (F30/F31/F32/F33/F36) OPF/GPF Evolution Link Pipe
The Akrapovič Evolution Link Pipe Set (SS) is designed to upgrade the Slip-On Line (Titanium) system to the Evolution System, offering enhanced performance and sound for vehicles equipped with a straight six-cylinder engine.
Key Features:
- High-Quality Construction:
Made from austenitic stainless steel, this link pipe set provides durability and improved performance over the stock exhaust system. - Dual Central Link Pipes:
Unlike the stock single-pipe design, the dual-pipe arrangement allows for optimal exhaust gas flow, improving both power and torque delivery while also reducing overall system weight. - Enhanced Sound:
The system produces a deep and sporty exhaust note, free from unwanted drone or streaming, while unleashing the pure sound of the straight six-cylinder engine. - Performance Gains:
The design of the Evolution Link Pipe Set not only increases performance but also improves overall vehicle responsiveness by reducing backpressure and increasing exhaust flow efficiency.
Installation and Compliance:
- Mandatory ECU Remapping:
After installation, remapping the ECU is required to prevent potential “check engine light” warnings and to ensure optimal system performance. - Track Use Only:
This product is designed for use on closed-course tracks and does not meet emission compliance requirements for street or highway use.
The Evolution Link Pipe Set is ideal for those looking to push their vehicle’s performance further, combining increased power and torque with a sportier sound for the ultimate driving experience.
