Description

The BMW M Performance Power and Sound Kit is engineered to unlock the full potential of B58-powered BMW models, specifically the F30 340i and F32/F33/F36 440i variants. This comprehensive upgrade includes a performance-tuned engine software upgrade that boosts power by 35 hp, bringing the total to 355 hp, and increases torque by up to 39 lb-ft (369 lb-ft peak for automatic, 355 lb-ft for manual transmission vehicles). The exhaust valve is electronically controlled and can be actuated in Sport/Sport+ driving modes via the vehicle's Driving Experience Control button, allowing for adjustable sound levels. Note that this kit does not include exhaust tips; separate purchases of Carbon Fiber M Performance Tips (ES2756082) or Chrome M Performance Tips (ES2698363) are required. This Power and Sound Kit is compatible with specific BMW models, including the F30 340i, 340i xDrive, F32 440i, 440i xDrive, F33 440i, 440i xDrive, and F36 440i, 440i xDrive, all equipped with the B58 3.0L engine.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
