AWE EVC Gen2 Exhaust Suite Catback System — F80 M3 / F82 M4 / F83 M4 S55 3.0T (2015–2020)Rename

Apex Verdict

The AWE EVC Gen2 Exhaust Suite Catback System is one of our Middle Tier catback selections for the S55 platform. If you know the F8X chassis, you know the stock exhaust leaves a lot on the table. This system transforms the car. It sharpens the tone, removes the thin factory note, and gives the S55 the deeper more aggressive character owners are actually looking for. Because this is an EVC system, you can toggle between different modes and control how loud the car is depending on the situation. Cold starts hit harder when you want them to, and with the valves adjusted the car can settle down for cruising when you need it to.

Why We Recommend It

The S55 can be tricky to get right. Cheap setups make it raspy and metallic fast. The AWE Gen2 system is engineered to deliver a premium aggressive sound while giving you flexibility. With the electronic valve control (EVC) you can switch between a more refined tone and a more aggressive open sound. Around town you can keep it composed. When you roll into boost or switch modes, it opens up and finally sounds like an M car should. For owners who daily their M3 or M4 but still want that proper aggressive tone on demand, this kind of control makes a big difference.

This sits in our Mid Tier pillar because it is a complete exhaust suite built specifically around the S55 character, now with integrated valve control. This exhaust system gives you the ability to adjust the sound profile depending on how you are driving.

Apex Insight

The F8X chassis is one of those cars where exhaust choice completely changes the personality. Having valve control means you are not stuck with one sound level all the time. You can cruise quietly when you need to and open it up when the road clears. That flexibility is what makes an EVC system like this feel right on a modern M car. It gives you aggression when you want it and control when you need it.
