There is no room for debate when It comes to the status of the BMW M4 as an exceptional car. With sleek and sharp sporty looks, nimble handling, a powerful and robust drivetrain, an exquisite interior, and a beautiful exhaust, the M4 epitomises the essence of a hardcore sports car. For some, the standard magnificence is not enough, and in the pursuit of perfection, they seek aftermarket gadgetry to further enhance their ultimate driving machines. The options are vast, and so to make that search for the best of the best a tad easier, I’ve put two exceptional exhaust systems head to head. Be sure to watch the video at the end of the article to see them in a direct comparison with the stock model.
The first contender is the Akrapovic exhaust system. Akrapovic is an top-notch brand, producing top-notch products, and this exhaust system is no different. Producing less back pressure, the system improves output power, and at the same time, by means of material selection, weight is reduced by 3kg. Overall, the system can achieve an increase of power up to 5.4kW, and an increase of torque up to 17.4Nm. All this power and technology, what does it amount to? It amounts to what can only be described as the sound of the petrosexual heaven. Putting your foot on the pedal unleashes a vicious harmonic of sound throughout the rev range, and when you release, an aggressive yet oddly calming hum emanates throughout the air, with the occasional crackle and pop as the revs reduce. I mentioned you lost 3kg with this system, although you should probably also consider the weight reduction when you take your stereo out. With a sound this perfect, you won’t find the need to listen to anything else.
Our other contender is the Hamann exhaust system. Like Akrapovic, the product comes from a reputable brand with reputable products to show for it. The particular stats of the Hamann system are, for some reason, quite difficult to get a hold of. But let’s be honest, while performance is an important aspect, with a car such as this, it is sound, not performance, which we are particularly geared towards as general consumers. The Hamann exhaust, when compared to Akrapovic, is like a post-pubescent adolescent, with a deeper sound throughout the range. It gives the car a greater sense of muscle and grunt, whilst maintaining that fine balance between tuner and racer.
All in all, I could not tell you which is the better system, as it is a completely subjective matter. One thing is certain though, and that is the fact that whatever system you decide to go with, you’ve made the right choice. For a final comparison, have a look at the video below, showing both systems, as all as the stock exhaust.
