The Slip-On exhaust system for the BMW 340i/440i is the result of the perfect integration of expertise, the best technology, and the use of the finest materials. It is made entirely of titanium and finished with two sets of newly designed handcrafted carbon-fibre tailpipes. This sporty elegance makes this Bavarian machine stand out from the rest and offers the taste of a more powerful vehicle, accentuated with the additional power gains and weight losses of the Slip-On exhaust system. The dual-mode ECU-controlled valve exhaust from Akrapovič offers a smooth, rich sound at normal cruising, and a deep, sporty, almost aggressive note when driving the 340i/440i more dynamically. It features a newly developed acoustic reflector (http://www.akrapovic.com/en/page/Akrapovic-Adjustable-Acoustic-Reflector) before the tail pipe that drivers can manually adjust if they wish to boost the sound in the cabin and enhance the joy of the driving experience.
The system is a simple plug-and-play operation to fit, and it has been designed to meet ECE type approval. The optional Akrapovič Sound Kit is also available.
For installing the slip-on system, the stock exhaust system has to be cut. Please read the instructions carefully before the start of the installation.
Slip-on Line (Titanium) can be used with BMW tow bar.

The Evolution link pipe set upgrades the Slip-On system to the Evolution system. The Evolution link pipe set is constructed from high-quality austenitic stainless steel. It features an arrangement of two central link pipes, which replace the single-pipe stock design for the best flow of the exhaust gases from the engine. It is designed to increase power and torque and reduce overall weight, while delivering a deep and sporty sound with no unwanted drone or streaming, unleashing the pure straight six-cylinder sound.
When installing the Akrapovič Evolution link pipe set, remapping the ECU is mandatory in order to prevent potential “check engine light” warning signals.
The high-flow downpipe is constructed using high-quality stainless steel and, once fitted to the Evolution Line exhaust, it creates a complete system from the manifold to the tailpipes that will further enhance the performance figures: both the torque and power outputs. It incorporates a sporty catalytic converter. This optional downpipe produces an enhanced sound that delivers a pure racing emotion and fantastic feedback at high revs, without unwanted drone, making it suitable for everyday use.

The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovič technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves.
Cars equipped with Akrapovič exhaust systems benefit from additional performance and increased responsiveness.
