The Gen 2 B58 (B58N) turbocharged inline-6 is one of BMW’s most capable modern engines, known for its immense tuning potential and smooth power delivery. However, factory catalysts restrict exhaust flow and limit turbo efficiency. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce backpressure, improve turbo spool characteristics, and unlock a deeper, more aggressive exhaust tone — all while maintaining emissions compliance standards.

The 2 series is the nearest embodiment of legacy BMW ideals in today's lineup. As such, in both the non-M and M trims, the series is continuously lusted after by the enthusiast community. While the G87 M2 may get the lion's share of publicity, the G42 M240i is equally as enticing and offers a robust value proposition for individuals looking to balance performance with comfort. Equipped with the latest B58 engine also found in the M340i and M440i, the M240i has performance covered in spades. Beyond the vaunted engine, the platform also borrows numerous other components from its 3 and 4 series counterparts. As such, it made sense to imbue the latest M240i with the same Dinan exhaust treatment the aforementioned models received and were heralded for -- an economical valved system with quad tips. Quad exhaust tips have been a signature feature of the most powerful letter in the automotive sphere for quite some time. It is a hallmark of the brand that Dinan has long embraced, limiting its own quad tip usage to those M cars that already sported like tip quantity from the factory. That is until the release of the Dinan exhaust systems for the G20 M340i and G22 M440i in 2019 and now extending to the G2 M240i today. While some may scoff at the feature being implemented into a "pseudo-M," the M240i, and the B58 engine platform, are extremely potent and worthy of such a distinction. The factory valance also accommodates the four massive 102mm tips perfectly, further cementing our opinion that the quad tips were destined to be on this performance model. Being numerous and big are not the only selling points to the tips however. Dinan has retained its signature straight cut tip design, safeguarding its unique and elegant styling position amongst a crowded marketplace full of angle cuts. With systems available with either black ceramic coated or polished clamp-on, and laser engraved exhaust tips, there is a version that is sure to meet your individual aesthetic needs. The use of quad tips also presented some additional challenges and fostered some innovation to the already visually impressive system constructed entirely of TIG welded and brushed T304 stainless steel. Confined to dual tips, the factory system utilizes only one exhaust valve and functions by eliminating the passenger side tip when the valve is closed, siphoning all gases through the muffler and out the driver's side tip for quieter operation. With the introduction of more pipes/tips, this methodology was not practical, or desired. In true Dinan M exhaust fashion, our talented engineering team decided that integrating a second valve to the system would garner the most favorable results in both symmetry and overall sound. The result is a system that incorporates larger 76mm tubing (vs 70mm stock) and allows freer flow through the entirety of the system but specifically to both outer pipes when the enlarged valves are open. The resulting flow and sound mimics an awe-inspiring straight pipe solution with a deeper and meatier tone, a defining element of all Dinan exhausts. In contradiction to the aggressiveness resulting from open valves, when the valves are closed, all gases are forced into the muffler for sound deadening and exit the two inner tips. Regardless of valve position, the intimate nature of the interior is retained so conversation can continue without an excessively loud drone courtesy of numerous drone abatement technologies in the can. With the Dinan exhaust equipped on the M240i you get the best of both worlds; aggressive tone/sound and civility. A combination that is paramount to any M exhaust, and now by virtue of tip count, the M240i as well. Welcome to the illustrious family. Features: More Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM Enjoyably louder, sportier sound Quad 4" diameter clamp-on, double-walled, polished and laser engraved exhaust tips 100% 304 stainless steel construction Larger diameter piping for increased flow (76mm vs 70mm) 4 pounds lighter than the stock system Stock exhaust valve actuator reused, and another valve/actuator added to the opposing side promoting even flow regardless of valve position Computer controlled exhaust valves are retained and limit noise during low speed driving and open fully during high-load conditions Twin exhaust valves are a whopping 76mm diameter, making them 30% less restrictive than the OE valves Factory-like fitment with included mounting hardware

FITMENT NOTE: An extra stock valve actuator (BMW # 18308686640) is needed when installing the Slip-On exhaust system on BMW M240i (G42). Offering 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-fiber tailpipes. Power and torque are increased by 7.1 Kw (9.7 hp) at 2,450 rpm and 20.5 Nm at 2,450 rpm when tested on the Akrapovič dyno against a BMW M240i with a standard stock exhaust. An exhilarating soundtrack is delivered through the use of special parts fitted into 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 Akrapovič 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.

For over 40 years, Active Autowerke has been at the forefront of BMW performance, and the G4X M240i axle-back exhaust represents the pinnacle of that development. This system is constructed entirely from TIG-welded 304 stainless steel, offering maximum resistance to corrosion and heat cycles. Unlike universal systems, this exhaust is engineered specifically for the G42 chassis, ensuring that every hanger and flange aligns perfectly. By retaining the factory valve control, this exhaust offers a "no-compromise" solution: it stays quiet and sophisticated when you need it, but opens up for maximum volume and performance when you want it. Each kit is a comprehensive package, providing all hardware required to transform your M240i’s rear section. Key Features: Surgical Precision: Every unit is test-fitted on a dedicated fixture to ensure zero-clearance issues with the chassis or diffuser. Premium Materials: Full 304 Stainless Steel construction ensures a lifetime of performance. OEM Integration: No need for extra wiring or controllers; works seamlessly with your car's computer. Aggressive Rear Stance: Fills the rear bumper cutouts more effectively than the stock rectangular tips. Performance Gains: Improved exhaust scavenging contributes to a more responsive B58 engine. Specifications: Type: Valved Rear Axle-back Exhaust Section SKU: 11-125 Finish: Brushed Stainless (Standard) Hardware: Includes all high-grade connecting hardware Vehicle Fitment: * 2022+ BMW M240i / M240i xDrive (G42 Chassis) Custom Options: Available in multiple tip finishes to match your specific trim package
