In a long line of aftermarket parts that are becoming available for the new BMW M4, exhaust systems are some of the most sought out aftermarket parts. While not as popular as other exhaust system companies, Innotech (or iPE) is definitely one of the best in the business. Innotech is the manufacturer of sophisticated performance exhaust systems specially designed for super cars such as Lamborghini, Ferrari, Porsche, and many others, and yes, BMW as well.
Their exhaust systems are custom built. They produced an unique sound for each one of their exhaust systems. It also allows the particular demands of the BMW M4 owners to be met by further developing the exhaust note.
Innotech’s valvetronic technology offers a sophisticated performance exhaust system that delivers both power and dynamic valve control to the driver’s seat. The full system includes the remote capability to command three different modes: open, closed, and auto. All three modes combine the electronic adjustment of the exhaust system by varying the settings according to the amount of fuel going into the engine, thus creating the optimum sound based on that. This means when the throttle is pushed down, depending on the setting, the sound remains either low or high, creating a comfortable ride when needed, but opening it up for a nice roar from the exhaust when the pedal is pushed properly.
Furthermore, the muffler internals were individually designed and produced for each different car in order to work well with the Valvetronic technology. To see the exhaust system in action, we’ve added a video below.
