X3M and X4M Valved Rear Axle-back Exhaust

BMW F97 X3M / F98 X4M Rear Exhaust Due to continued requests from our customers, Active Autowerke is pleased to release the Active Autowerke Valved Rear Exhaust for the X3M and X4M. While these SUVs have received rave reviews for their performance, the sound is a muffled one leaving the driver to wonder if they are really driving a BMW M-car. In order to solve this, Active Autowerke has created a full exhaust system for the X3M/X4M which comprises this rear axle-back valved exhaust, a single mid-pipe and a set of GESI catted downpipes. Together, this remake of the stock exhaust results in a F97/F98 with an amazing sound. You will feel like you are driving a true M-car again. At Active Autowerke, it's not ONLY about making as much power as possible but to maximize the enjoyment of the drive. For over 40 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best rep
