Dinan 23-26 BMW M240i/M240i xDrive (G42) Valved Axleback Exhaust System - Black Tips

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. Stainless Steel - Black Tips - G42

• 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
• Quad 4" diameter clamp-on, double-walled, black ceramic coated and laser engraved exhaust tips
• Larger diameter piping for increased flow (76mm vs 70mm)
• More Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM
• Factory-like fitment with included mounting hardware
• 4 pounds lighter than the stock system
• 100% 304 stainless steel construction
• Enjoyably louder, sportier sound

Upgrade your BMW M240i with the Dinan 23-26 G42 Valved Axleback Exhaust System, crafted from 100% stainless steel and finished with sleek black tips for a sporty appearance. This exhaust system features larger 76mm tubing, providing significantly freer airflow compared to the stock 70mm pipes, resulting in more power and a deeper, more aggressive tone. The system's dual exhaust valves are computer-controlled, allowing seamless transitions between quiet cruising and full-throttle sportiness, making it ideal for both daily driving and spirited performance. When closed, gases are rerouted through the muffler for noise reduction, ensuring civility during low-speed driving, while open valves unleash a roar reminiscent of a straight pipe setup, enhancing the vehicle's commanding presence. The quad 4-inch black ceramic-coated tips are double-walled and laser-engraved, adding a refined aesthetic that complements the exhaust's performance attributes. Installation is straightforward with factory-like fitment and included hardware, and the system weighs approximately 4 pounds less than the stock exhaust, contributing to improved handling and efficiency. This exhaust system not only enhances sound and style but also delivers a modest gain of +6 horsepower and +5 lb-ft of torque at 6600 RPM, elevating your M240i's performance profile. Whether you're aiming for increased sound, improved airflow, or a custom look, this Dinan exhaust system offers a balanced combination of sportiness and civility, making it a perfect upgrade for enthusiasts seeking both form and function.
