BMW M4 Akrapovic Slip-on Exhaust vs Fi Exhaust

The BMW M4 is indeed a beast in its own right with the high performance it delivers stock. But when it comes to its stock s55 engine sound, there is a lot left to be desired.

Akrapovic jumped into the F82 and F83 market with its Slip-On exhaust system, ensuring their exhaust system would take the BMW M4’s exhaust sound to another level.

Around the same time, we saw a high-performance Frequency Intelligent Exhaust hitting the market. This system is made of T304 stainless steel giving you an amazing sound while you drive.
