The Akrapovic Slovenian based exhaust maker has recently released the Slip On and the Evolution exhaust systems for the high-end models BMW M3 and M4 models.
First, the Slip On exhaust can be available from $4,591, being manufactured from titanium and having bigger pipes than a standard exhaust, which leads to increase power and lower back pressure.
The system is highly performant as it reduces the overall weight of the car and delivers more throttle and a sporty sound, which leads to improved acoustics.
In case you want to upgrade the Slip On exhaust, you can add up titanium or carbon-tailpipes, as well as a carbon-rear diffuser.
On the other hand, the Evolution performance exhaust system is priced at $6,731 and comes with a single-central muffler, adding valves and much bigger link pipe tubes, all increasing the performance of the car.
The Evolution exhaust is built to give the M3 or the M4 a smoother flow, as it is entirely made out of titanium, which gives it one of a kind sound.
Also, no ECU re-programming is required for the Evolution system, as it does not initiate any warning lights.
