The ARM M240i Midpipe significantly improves the acoustic character of your B58 engine, delivering the commanding exhaust note desired by enthusiasts of tuned B58-powered BMWs. Crafted to enhance both the performance and auditory experience of your B58 engine, the ARM M240i Midpipe achieves this by removing the two central resonators present in the stock M240i midpipe.

What's remarkable is that with the ARM M240i Midpipe, you retain the original equipment manufacturer (OEM) muffler, granting you complete control over the exhaust volume. When you engage Sport Plus mode, you'll revel in the heightened symphony of the upgraded B58 engine as it sings with a newfound vigor. Conversely, a simple switch to comfort mode allows you to maintain a quieter presence while driving through residential areas.

For those seeking the pinnacle of volume and weight reduction, you can upgrade to the ARM Single Exit Exhaust. 

Construction:

Designed in-house and rigorously tested on ARM's M240i, the ARM M240i Midpipe boasts impeccable fitment, aligning perfectly within the vehicle's exhaust recess. Engineered to sit at or above other car components, it ensures ample clearance, even on lowered suspensions.

The ARM M240i Midpipe is versatile, accommodating both the OEM downpipe and any compatible upgraded downpipe designed for the OEM midpipe. During spirited driving, it securely attaches at the OEM mid pipe mounting location, ensuring stability and confidence.

Comprising two distinct sections—a longer front section and a shorter rear section—the ARM M240i Midpipe connects seamlessly through a slip-fit style connection, firmly sealed with high-quality performance-grade exhaust clamps.

A standout feature of the ARM M240i Midpipe upgrade is the removal of the two OEM resonators, liberating the captivating sounds of the B58 engine. Maintaining a consistent 3.25" diameter throughout, from the downpipe to the muffler, it delivers an unobstructed auditory experience.

For those seeking an enhanced sound profile and substantial weight savings, the ARM M240i Single Exit Exhaust is the ultimate solution. Replacing the entire OEM setup it results in an impressive reduction of over 20 pounds in weight, further elevating the vehicle's performance and personality.
