BMW of North America introduced earlier today two new aftermarket kits for the BMW 340i and 440i models. For the first time, the BMW M Performance Power kit now comes bundled with a higher flowing, valve controlled exhaust for maximum performance and exhilaration. The BMW M Performance Power & Sound Kit features engine tuning software and an electronically controlled valve exhaust system that is actuated in Sport/Sport+ modes via the driving experience control button.

The power kit brings the total power output to 355 horsepower, a 35 hp increase over the stock engine. Torque is also increased to 369 lb-ft (+39 lb-ft) for automatic transmission vehicles and 355 lb-ft (+25 lb- ft) for manual transmission vehicles.


The kit also provides faster acceleration: 0.2 seconds faster than the standard 340i/440i model from 0 to 60 mph.

BMW says the new power and sound kit adheres to the BMW test standards, therefore the cars equipped with the kit retain the emission certification and original fuel efficiency ratings. The vehicle’s original warranty is not affected.

The MSRP for the BMW M Performance Power & Sound Kit is $2,820. It requires exhaust pope finishers, the stainless steel one is priced at $128 each, while the carbon fiber sells for $254 each.
