Is this Akrapovic BMW M440i exhaust system street legal?

No. Although it's built around Akrapovic's Slip-On Line muffler, this kit is bundled with the Evolution stainless steel link pipe, which is required for installation. The complete system does not meet sound or emissions compliance requirements for street or highway use and is intended for track use only.

What's included with this kit?

This kit includes Akrapovic's titanium slip-on muffler with hand-crafted carbon-fiber tailpipes, dual valves with a TNG controller, and the required Evolution stainless steel link pipe. You'll also need BMW's factory valve actuator (p/n 18 30 8 686 640), ordered separately.

Does this fit the BMW M440i Gran Coupe?

No. This system is designed specifically for the G22 M440i Coupe and G23 M440i Convertible, including xDrive. The M440i Gran Coupe uses a different chassis (G26) and isn't covered by this listing — check with us before ordering if you drive a Gran Coupe.

How much weight and power does this BMW M440i exhaust system add?

The complete titanium system weighs 21.7 kg, about 23% lighter than the stock exhaust, and adds up to 8.7 kW (11.8 hp) at 5,600 rpm and 17.1 Nm of torque at 4,100 rpm. ECU remapping is recommended to make the most of these gains.

Will this fit a European-spec M440i with a particulate filter?

No. This system is designed for non-OPF (particulate-filter-free) vehicles, which typically means US-spec M440i models. European and UK OPF/GPF-equipped cars aren't compatible with this configuration — contact us to confirm your vehicle's spec before ordering.

Description

Akrapovic Titanium Slip-On Line w/ Evolution Link Pipe for G22 G23 BMW M440i

Akrapovič’s BMW M440i exhaust system pairs its Slip-On Line muffler with the required Evolution stainless steel link pipe, hand-crafted carbon-fiber tailpipes, and dual valves controlled by an included TNG controller. This is a track-focused performance system, not a street-legal slip-on — the bundled link pipe brings real weight savings and power at the cost of compliance.

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.
