Does the Akrapovic Evolution Line for BMW M440i fit OPF/GPF-equipped cars?

No. The Akrapovic Evolution Line for BMW M440i is built for non-OPF vehicles only. On cars fitted with the factory particulate filter the housing and pipe routing do not line up, so the system will not install correctly. Check the build sheet or ask a BMW dealer to confirm your car's OPF/GPF status before ordering, because the two configurations are not interchangeable.

What's included with the Akrapovic Evolution Line for BMW M440i?

The kit ships as a complete system replacing everything from the factory downpipe back: the titanium muffler with hand-crafted carbon-fiber tailpipes, the austenitic stainless-steel link pipe set, and the TNG electronic controller that activates the extra exhaust valve. The factory downpipe is retained and is not supplied. The Akrapovic Sound Kit is a separate accessory and is not part of this kit.

Is this exhaust street legal?

No. Akrapovic states the system does not meet emission compliance requirements for street or highway use and carries no valid ECE type approval on non-OPF vehicles, so it is built for track use. Akrapovic also recommends an ECU remap after installation. Confirm local noise and emissions rules before running the car anywhere other than a closed course.

How much power does the Evolution Line add to the M440i?

Akrapovic's dyno testing shows gains of up to 8.7 kW (11.8hp) at 5,600 rpm and 17.1 Nm of torque at 4,100 rpm over the stock system. Smaller gains arrive much lower in the range, from around 2,650 rpm, so the B58 pulls harder in everyday driving as well as at the top of the tach.

What is the Evolution Line made from, and how much weight does it save?

The system uses a titanium main structure, hand-crafted carbon-fiber tailpipes and an austenitic stainless-steel link pipe set, with the cast components produced in Akrapovic's own foundry in Slovenia. Complete, it weighs 21.7 kg (47.8 lbs), which is 4.4 kg (23%) lighter than the factory BMW exhaust and takes that weight off the rear of the car.

Do I need to remap the ECU after installing this exhaust?

Yes. Akrapovic recommends an ECU remap after installing the Evolution Line so the engine management works correctly with the added valve and the freer airflow. Budget for tuning as part of the installation rather than treating it as an optional extra, and use a tuner familiar with the B58 and with Akrapovic hardware.

Description

Akrapovic Evolution Line for BMW M440i in Titanium with Carbon Tips and Link Pipes

Akrapovic’s Evolution Line for BMW M440i pairs the titanium construction and in-house foundry work behind Akrapovic’s reputation with a complete system that replaces everything from the factory downpipe back: link pipes and hand-crafted carbon-fiber tailpipes engineered specifically for the G22 and G23 platform. Every component, from the two tuned resonators to the acoustic reflectors built into the tailpipes, comes out of Akrapovic’s own titanium foundry in Ivančna Gorica, Slovenia, the same facility behind exhaust technology credited with 38 world championships across MotoGP and World Superbike. The result is a system 4.4 kilograms lighter than the factory setup, with up to 11.8 hp and 17.1 Nm gained over stock, and a deep, layered inline-six voice with none of the drone that plagues cheaper full systems. This is a track-focused build for the M440i owner who wants the sound and response of a factory-backed racing exhaust, not a daily-driver muffler swap.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
