Does the Akrapovic Slip-On Line for F97 BMW X3 M also fit the X4 M?

The muffler and link pipe are shared, so the Akrapovic Slip-On Line for F97 BMW X3 M uses the same base system as the F98 X4 M. What differs is the carbon tail pipe set, which is cut for each car's rear bumper. Akrapovic lists the F97 for 2020-2024 and the F98 for 2020-2026, so confirm chassis and model year before ordering.

Does this exhaust work with the factory OPF/GPF emissions equipment?

Yes. Akrapovic built this system to work alongside the factory Otto Particulate Filter and Gasoline Particulate Filter equipment, and it leaves that hardware in place. Nothing in the emissions system is disturbed during installation, so there is no missing component to set a check-engine light. Cars built without the particulate filter need Akrapovic's Evolution Link Pipe Set as a mandatory extra part.

How much weight does this system save?

Akrapovic's titanium construction saves approximately 24 lbs over the factory steel exhaust, taking that mass out of the rear of the vehicle. The saving comes from the muffler and link pipe rather than from thinner-walled pipework, so durability is unchanged. Titanium also holds its finish better than steel under repeated heat cycling.

How much power and torque does this exhaust add?

Testing shows a gain of +7hp and +11 lb-ft of torque over the stock exhaust system. Actual gains vary slightly with the condition of the vehicle and any supporting modifications already fitted, and on the S58 the more noticeable change is throttle response and the sound under load rather than the peak figure.

Does this exhaust retain the factory sound-mode switching?

Yes. The Slip-On Line keeps the factory-style dual-mode exhaust valve, so the vehicle stays quiet and civilized in normal driving and opens to a sharper, higher-frequency tone at higher RPM. Drone is engineered out at cruising speed, which is what separates it from cheaper axle-back systems on the same chassis.

Is this exhaust street legal?

Akrapovic does not publish an ECE type-approval or emissions-compliance certificate for this system. Because it works with the factory OPF/GPF equipment rather than replacing it, most owners fit it without trouble, but confirming local noise and emissions rules before installation remains the owner's responsibility.

Description

Akrapovic Titanium Slip-On Line for F97 BMW X3 M and F98 BMW X4 M

Name: Slip-On Line for F97 BMW X3 M | Bulletproof Automotive
Brand: Akrapovic
SKU: S-BM/T/10H-CX4
Price: 6829.81 USD
Availability: BackOrder

Akrapovič’s Slip-On Line brings its titanium exhaust technology to the BMW X3 M and X4 M without touching a single factory emissions component. Built entirely from titanium and retaining the S58’s factory dual-mode exhaust flap, this system keeps the muffler’s civilized, deeper-than-stock character at low RPM and around town, then opens up into a sharper, more aggressive note as the revs climb — all while working in conjunction with the OPF/GPF hardware BMW builds into these cars. It’s a straightforward, plug-and-play upgrade from the same in-house foundry and motorsport engineering behind every Akrapovič system, finished here with bundled carbon-fiber tips.

Design and Performance

The Slip-On Line replaces the axle-back section with a titanium muffler and link pipe while keeping the factory-style dual-mode valve control, so the exhaust stays quiet and refined in daily driving and switches to a livelier, higher-frequency tone under load; Akrapovič casts the valve housings at its own foundry rather than outsourcing them, the same process used across its motorsport-proven lineup.

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.
