Offering a noticeable weight savings, increased power and torque, and a dramatic soundtrack, this system is constructed from lightweight high-grade titanium and completed with hand-crafted carbon-fibre tailpipes. The system offers an 11.89 kg savings over the standard stock system, an incredible difference of 33%. Power and torque are increased by 3.4 Kw (4.6 hp) at 2,650 rpm and 12.4 Nm at 2,650 rpm when tested on the Akrapovic dyno against a BMW M440i with a standard stock exhaust. An exhilarating soundtrack is delivered through the use of special parts fitted in the system. Two valves – instead of one, as in the stock configuration – are calibrated to tailor the sound, and two acoustic reflectors are fitted on the tailpipes to guide the sound into the car’s cabin and change the driving experience, producing a fully immersive sound in the car’s cockpit, to supply thrills and enjoyment that can be enjoyed by all occupants. Because the Akrapovic Slip-On Line (Titanium) exhaust system has two valves, one more than the stock configuration, a TNG controller is included in the product to activate the additional exhaust valve. Two resonators, one on each side of the central muffler, perfect the sound experience. The smooth, rich sound at normal cruising rises to a deep and sporty soundtrack when driving more enthusiastically, and the tones can also be controlled from within the cockpit with addition of the optional Akrapovic Sound Kit. Special parts are cast in the Akrapovic in-house foundry to create the intricate and complex items needed for this system. It meets ECE type approval, and no remapping is needed for this configuration (the system only fits vehicles equipped with the OPF filter, and the ECE certificate is valid only for these cars; for non-OPF vehicles, an Evolution Line system is available). An optional link pipe set is available for those customers looking for an upgrade to the Slip-On Line (Titanium) exhaust system.
Fitment notice: This product fits on the BMW M340i equipped with an OPF.
An extra stock valve actuator (part nr. 18 30 8 686 640) is needed when installing the Slip-On exhaust system on BMW M340i (G20, G21) and M440i (G22, G23, G26).
This product also fits on the BMW M340i xDrive Touring (G21) model.
We accept no compromises! The company’s vision was clear from the very beginning, and we have not faltered. What started as an innovative,
driven group of six, is now a modern prominent company of more than 13,000 m2 of production and commercial space and with 450 employees, all of us aware that we produce exhaust systems for customers who simply do not accept mistakes – the most demanding racing teams and riders from around the world.
Only the best is good enough for us. But the best is not just the exclusive privilege of the factory teams. Now it is available to everyone!
An exhaust system looks simple at first glance. But a closer look shows that it is a complex system that has a significant effect on the performance of a racing or a regular sports car.
The experience in racing that we acquired over many years, taught us how to combine high performance, a long-life cycle and the lightest possible weight. Our numerous world championship titles and countless international and national titles are a testament to our continuous ability to fulfil our clients’ highest expectations.
- Lightweight
The titanium we use for our exhaust systems is produced exclusively for us. It is three times stronger and is more heat resistant than any other titanium product on the market and 40% lighter than stainless steel. The high strength allows us to use thinner insulation while still achieving the highest quality standards. In fact, this brings our clients the decisive advantage on the race track.
- Performance and quality
Our goal is to make the perfect torque and the perfect power curve. Our research and development department is provided with the latest equipment, so that they are able to combine their collective know-how obtained at many race tracks and even Formula 1, and apply it in practice.
WARNING:
Please note that certain aftermarket exhaust systems may not comply with applicable California laws and regulations, and may therefore be prohibited for use on California highways or roads, or on roads or vehicles otherwise subject to emissions control requirements.
Akrapovi? exhaust systems for automobiles and motorcycles mounted downstream of the catalytic converter (also known as “cat-back systems”) are considered “replacement parts” in California by the California Air Resources Board (CARB), and do not require an exemption or executive order from CARB to be sold in California. However, California prohibits the use of any aftermarket exhaust system that modifies, removes or replaces original equipment catalysts, unless CARB has issued an Executive Order as to such part or system.
Further, Akrapovi? parts or exhaust systems used or intended for use on “racing vehicles” (i.e. a competition vehicle used exclusively for competition on closed-course circuits) do not require an exemption or Executive Order from CARB to be sold in California. However, such parts are prohibited from use on California public highways or roads, even if occasionally used “off-road.”??
