Active Autowerkes Cat-Back Exhaust System For BMW X4 M

Description

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 represented by the introduction of F97/F98 BMW X3M/X4M collection rear exhaust. The Active Autowerke F97/F98 rear exhaust was carefully engineered to increase the sound level over the factory X3M and X4M exhaust, while also allowing for optimum flow and resonance by reusing the actuators from the BMW valves. Every effort was made in addressing the overly quiet sound of the stock OEM exhaust while designing an exhaust worthy for an “M” car. We believe our rear exhaust combined with our mid-pipe and catted downpipes offers the best combination of sound and performance versus any other system on the market today. Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory!
